Driveshaft arrived today and it's in. Great fitment,  excellent workmanship and turnaround time. I appreciate your extensive communication and effort made to get it right the first time. My old friend is back on the road with me again. Thanks again and pass on my appreciation to your shop.
Thanks again,

Hey Brent,
I received my driveshaft today and just wanted to say this thing is BEAUTIFUL! Kind of hate to hide it underneath my car. No, really excited to get it installed and get my ’57 Chevy back on the road. I just wanted to thank you for the quick service and what looks to be a fantastic driveshaft. Thanks.

2004 F150 4x4   Brent, just put in driveshaft(after a little delay by UPS), fits perfectly, truck runs great. Thanks to you and your entire team for such quick and professional work, I'm telling anyone who will listen about your company.             Thanks again, Kevin B, Hudson Falls, N.Y.

Brent…are you kidding me? I got hung up at an an appointment and as the paypal payment request come in but I could not take care of it at the time. I had a UPS tracking number before I even payed for it. You guys are a CLASS ACT. On such a small order you guys really shined. As a honest small business owner I really got to say I am very happy with the experience I had with you all.
Kindest Regards

2005 Chevy 1500 with 2 pc conversion from Alum for hi-speed,  Brent & DSS crew,  I want to send you a big thank you and Aloha!  I got the pinion yoke and driveshaft installed and what a major improvement in my driveline!  I'm not sure if I mentioned this before, but I originally had a 86+" tin can aluminum Oem driveshaft in my Silverado that would shake badly at higher speeds.  I did a 2 piece steel conversion using junk yard shaft.  What a waste of money, it hummed @ 60mph/highway speed.  That's when I got in contact with you guys.  You have always responded to ALL my emails and questions, even though I'm from far away Hawaii.  I received your shafts and didn't want to install it because of its quality and it looked so pretty.  All in all, my driveline has no vibes and my family and I feel safe not having to worry about bunk DS.
Thanks and Aloha, Jet

Ball and Trunnion Conversion  

I purchased a Drive shaft from you several months ago to replace the Ball and Trunnion style drive shaft on a 1965 Plymouth Barracuda.  Before calling I had spent several hundred Dollars rebuilding the old drive shaft twice.  Each time the thing would last a couple of weeks before the vibration started again and it became unusable very quickly.  When I called your place of business the staff was very helpful and professional and helped me get the things I needed to properly place the order.  I was told there were a lot of orders ahead of me but was still very pleasantly surprised when the new drive shaft arrived 5 days later which was way sooner than I would have expected considering you build them from scratch.  The product I received was very well made and was as good in appearance as anything I have ever purchased.  I was able to get in installed in about 15 minutes with no issues.  The real payoff was the first time I took it down the road. The previous vibration and noise form the original drive shaft was completely gone and the ride of the vehicle  was smooth and quiet.  The 4 speed shifter seemed to operate more smoothly as well.  I was very pleased with the purchase and have told many people where the drive shaft came from.  It has been on the car for many months now and is still working as well as it did new.  In the process of restoring this car I have purchased many items.  A lot of them have fallen very short of what I expected and I had to replace them.  You guys do really professional work and I appreciated the value I received for my money.Thank you, Steven C

2006 Ram 2500 4x4   Morning Brent,   First of all, thank you so very much!  If you were here right now I'd hug you!  Got my drive shaft yesterday and got it on my truck.  WOW, what a world of difference that thing makes, and the finished product is unbelievable.  I never knew what smooth take offs were until now, all shudder and vibration is gone.  You and your company are A1 in my book, and I'll recommend y'all to anyone.  Thanks again for the quick turn around, and the professionalism you showed with me.  Have a great day.John (Mike) J.


5.0 Alum shaft in 2008 GMC 2500 HD  Hi Brent,
  I just received and installed the driveshaft you made for my 2008 GMC 2500 HD. I put it in and took it out on the freeway and ran it up to 90 mph with no vibrations at all. Very smooth!  Thank you. I will definitely be recommending your company to others. Thanks, Chris  in OHIO.

BMW Driveshaft  Brent,  Drive shaft turned out great!  Car feels so much better.  She just a 318is but built handle.  All coil over suspension, polyurethane bushings all way around upgraded m3 brakes, stainless brake lines, stage 1 lightweight flywheel and HD clutch.  Looking to build a obd1 325 motor and turbo it in the fall.  And now a well balanced driveshaft, all the vibration gone!  I think my brother m3 needs to be done soon. I will be sending it to you guys for sure!!

Thanks again Chucks 318i BMW



2011 F250 4x4   Just wanted to say that I got my driveshaft in today and I am very pleased. The whole process was great and your company was very helpful and understanding over the phone. I could not have asked for better service. To whomever it may concern I just wanted to say thank you for all the help and your company will be recommended by me from here on out.

You guys are GREAT! After trial and error repair on an '06 F-150 drive line, I found your company on-line. Made the call, took the measurements (simple), placed my order Monday at noon and received my new driveshaft on Thursday (Christmas Eve). Bolted it up and..... Wow! Smooth as silk. Thank you so much. Ford problem solved. I'll definitely be referring everyone to

I received my custom 4 inch, .125 wall aluminum driveshaft complete with the Sonnax slip yoke and 1350 Spicer U-joints, correctly sized for 9000 rpm use and high torque. I reserved my comments until I fitted the shaft in place, and it fit perfectly with exactly 1 inch axial slip as I had specified. What a beautiful piece of craftsmanship! It was painted white as I requested. Uniform welds, a second-to-none quality “black chrome” slip yoke, and based on the very small balance weights used for high speed balance, it is a straight tube with excellent build concentricity. Your customer support was cordial and knowledgeable, your turnaround time minimal. Very good price and worth every penny!Thanks again,Keven Van Duyn Bluestone Racing  Bloomfield, Ct.


I have a 2006 Ram 2500 Mega Cab w/Cummins. I finally got tired of my 2 piece Mopar driveshaft. I learned that after a few rebuilds that trying to save a buck just is not worth it. After installing new u-joints and carrier bearings it still had shudder and vibration around 35 and then again at 65. I did my research, skipped the middle men and went straight to the source. I cannot thank Driveshaft Specialist enough. I ordered my driveshaft just before close of business on a Friday. The following Tuesday I called you with my emergency which was not your problem. Instead of getting told tough luck you guys bent over backwards and got my driveshaft built and sent out Wednesday with overnight delivery to Indiana. Even after calling you back a couple times to check on progress you remained polite. I have honestly never done business with a better company and your craftsmanship is second to none. The shudder and vibrations are completely gone.

2004 Dodge 1500 2wd  Hi Brent and Jeff,
I wanted to let you know that I received my new drive shaft today and everything looks great! Already installed it and it fits perfect. THANK YOU! I can't say that enough for helping me with my complicated situation.  Tony G

Driveshaft for 2006 F150 FX4 126 inch WB 4x4  Thank you for your driveshaft.  It fit perfectly and has greatly improved my ride. Boyd F.

BMW race car - custom build.  Installed the driveshaft nd I wanted to let you know my thoughts:

1) The driveshaft looked great, all bits looked and felt great, and once it was installed, my car was noticeably smoother running. The car is a fully prepped Street Touring car for SCCA autocross -- poly motor/tranny mounts, etc. -- so there's a lot of vibration, etc.

But, as I said, the car was noticeably smoother running your driveshaft.

2) The install was painless as can be expected. Everything fit perfectly, etc.

In fact, your driveshaft solved a problem I'd had in my car. The front section of the BMW OEM driveshaft incorporates a widened section that is problem 4 inches in diameter. That wider section contacted my short-shift kit, forcing me to shim the transmission bracket and center support to gain clearance.

On your driveshaft, that wider front portion wasn't AS wide as mine, probably only 3 inches in diameter or thereabouts. Bottom line, clearance problems solved!

3) The pricing and service were fantastic.

In conclusion, thanks so much, Driveshaft Specilaist!

BMW Driveshaft  Hey Brent, just wanted to let you know that the driveshaft I received this morning is perfect! Thank you so much for going to the lengths that you did to appease me. You went above and beyond what I expected and I cannot thank you enough. Your customer service is top notch. I will defiantly be recommending you guys to anyone and everyone looking for a driveshaft. There simply aren't companies anymore that take care of their customers as well. Thank you so much, Aaron. 

1965 Chevelle w/ TKO 600   Hello Jeff,
Just wanted to let you know I got the modified drive shaft installed without issue. Yoke is in with about an 1" between the trans tail housing and the yoke flange. Seems solid with no movement. Really appreciate all your help with getting me squared away. I will let others know what great service DSI provides!
Kind Regards,

99 Dodge 2500 with manual trans conversion  Sweet baby Jesus. The driveshaft fit perfect! I was worried about purchasing a custom made part from a 1000 miles away but the process was seamless and now I have driveshaft that will last the life of my truck. Thanks again for the quick build, extreme professionalism and dedication to making a solid product. I will certainly praise yall on the forums when I do the write up about my manual conversion. Yall have a good weekend.  Jason H.

2011 Ram 25004x4  Hi There,
 Just wanted to let you know that I just received the driveshaft that you made up for my 2011 Ram 2500. 
  Upon initial inspection, I was impressed with the quality right out of the box, the welds looked better than the factory Ram shafts, the entire shaft looked excellent. And we are a machine tool dealer / machine shop, so I have a lot of experience in that sort of thing.
 And it gets even better, after I installed it, there was a huge difference that I noticed as soon as I pulled out of the parking lot. I have done the aluminum shaft conversion on another Ram truck before, but I forgot how much difference it makes. It is unbelievable how much it smoothed out the ride. I have a manual transmission, and getting rid of that extra joint in there makes a big difference in the feel and tightness of the transmission to driveline connection. Everything about it is just better, no question about that.
  I would highly recommend your company to anyone, feel free to use me as a reference if you ever need to. There is not a single bad thing that I can say about you. 
 Thank you!

Hi Brent,
Just a quick note to let you know that I got the driveshaft installed over the weekend, all went well and, more importantly, it solved the issues I'd been having, which is fantastic.
I shipped the core back yesterday, thought you'd be amused by the redneck driveshaft delivery method I employed to get it back to UPS (see attached pic).
Thanks for an excellent product and transaction, you guys are a pleasure to work with and made what could have been a real hassle into a simple exercise, much appreciated!Cheers,  Greg E.Hi Brent,

Joseph F again I received my driveshaft today and I will say that this shaft is one quality piece of work I love it and it is everything I expected it to be thank you so much sincerely Joey

Just wanted to thank you all for the excellent craftsmanship on my new driveline for my 06 dodge. It fit perfect right out of the package! Now my truck has no more shudder on takeoff and no vibration at all going 70 down the highway. Thanks again!! Will recommend your shop to anyone!!

Hi there. I have a 1965 Plymouth Sport Fury convertible with the original Commando V8 and an A833 4 speed transmission. Two weeks ago the original ball and trunion joint at the front end of the driveshaft finally gave out. I searched for a solution to my problem for a week without much luck. I decided to replace it with a more modern style. From the time of order to delivery to Canada, was just over a week. Admittedly, I was a little skeptical about its fitment, but wow! I am so happy right now. Everything, and I mean everything fit perfectly! The bolt holes at the flange were perfect, the length was perfect, the fit and finish was beautiful, and it is balanced perfectly. I can honestly say that there is not one thing that I would have liked to see different. Thank you so much for a great product, delivered on time at a great price. You obviously know what quality and customer service mean. Here's a pic of the car it's on. Feel free to add my letter and/or picture to your testimonials page.

Bruce H. (2000 Ford Excursion 4x4)
I just had to write to thank you guys. I talked to Jeff Dusek on the phone for about 15 minutes. He took the information that he needed, and told me there is a 2 day backlog. I didn't know how ordering a driveshaft through the internet was going to work out, but I couldn't get a new one from Ford, discontinued. It came yesterday in a very protective package. I installed it, without any difficulty, and it fit perfectly. It is a little different than the original, but Jeff had told me it would be, I think, for the better. I am very pleased at the professionalism, and service I received from Jeff and your whole company. If ever I run into someone who needs driveshaft work, your company is tops on my list of recommendations. Also, your pricing is exactly what I would expect to spend on a new driveshaft. Again, thanks a bunch for a pleasant experience.

I just wanted to send a quick message to say Thank You!  The drive shaft bolted right in, looks great, and it's nice to finally be rid of that 55mph + vibration!  The turnaround time was absolutely impressive!  Thanks!

07 Ram 3500 1480 shaft   Wow. Awesome service, it is here already. If there is anything I can do for you guys just let me know. Thank you Jeff and shop guys.   Jonathan N.
Hi Brent,
I've been running with the new driveshaft about 2 weeks and it's working out great!!!  Whether I'm going 8 or 80 mph....No more drive train vibration.
The old drive shaft was was over 1.5 inches shorter than the new one which explains the vibration issue I was having.  Thanks for your help and excellent service!!!
I attached a few pictures.  My truck has a dump box so you have a great view of the driveshaft when I raise it up.Thanks Glenn55 Chevy Truck  Glenn V V.


2011 Ram 25004x4    Just wanted to say thanks a ton for this quality driveshaft. It took me about 10 mins to put it in. Fits like a glove. After letting my thread lock set up i took it for a test drive. It was so smooth by the time i looked down i was going 100. No joke. Thanks again. 2011 Ram 2500 John HJohn H.


BMW 325i    Driveshaft Specialist,
I wanted to extend my appreciation for a job well done.  I ordered my rebuilt driveshaft for my 1990 BMW 325i over the phone in the fall of 2013.  The gentleman who took my call was friendly, knowledgeable and efficient.  We joked around about the poor weather in Texas at the time and he was still professional and courteous despite the ice storms in the area.
My driveshaft arrived at my doorstep before the promised delivery time.  It was packaged well to prevent damage.  The craftsmanship and the paint on the shaft itself made it seem like I ordered a new shaft from BMW!  The arrow stickers showed me where to align the two halves if needed (which I did not).  
When I finally got around to installing it, the shaft went in with no issues and my car is back on the road.  I shipped the old shaft back and received my core discount on my credit card as promised.
Thanks to Driveshaft Specialist for a great customer experience all around.  I cant wait for the snow to melt so I can take my car on the highway and feel that smooth power delivery again.Jordan  Oak Park, IL
1997 Trans Am  Hi Jeff, 
I received my driveshaft last week, and must say I'm one very satisfied customer! The weight difference over the stock driveshaft and my custom driveshaft is remarkable. I was able to grasp and lift my new three inch aluminum driveshaft with my thumb and index finger! I could not perform that feat with my 2-1/2 inch stock unit.
I installed my new driveshaft within a couple of hours of receiving. Everything mated up nicely. The entire job took about 30 minutes.
I was finally able to safely accelerate up through 90 mph and it was smooth as silk! Pushing it through the triple digits I'm confident  would have been just as smooth! This also confirms my ring and pinion install (3.90) was successful.
 This unit is an awesome piece of machined technology when compared to my old driveshaft. I'm extremely happy with the results, and it's money well spent!
 Thanks!  Greg A.
1995 Ram 2500 in Alaska  Brent & Jeff:    Snow forecast for today. S’posed to be about a foot of it. I crawled under the truck for the last time, made a coupla adjustments and checked everything a fourth time as a few flakes started falling. I plugged ‘er in as soon as I got up to wake and warm the mill. Crawled behind the wheel, prayed a moment or two, softly spoke two words to the truck: “Junk Yard.” And turned the key. She lit right off, and four months of backbreaking work paid off. Everything works. I need to adjust the transfer case linkage, but that’s all. Only way out is uphill, and I needed to be in 4x4 to go up in the deepening snow, and had zero problems.  One note: with the old Gear Vendor overdrive, when I’d decelerate, the driveline would clang. With it gone, the new driveline makes no noise on deceleration. I can’t take it up to highway speeds just yet(not smart on snow & ice), but everything works as advertised.

  You guys hit it right on the head. I had a bit over an inch of play upon installation.

    I crawled back underneath and reattached the skid plate as serious snow started blowing under the truck. Windows in the house are now white from driven snow, and it’s now blowing 40 out. One last trip into town yesterday, and I put the motorcycle in the shed last night, thinking it was time.  I don’t believe I could have ducked that bullet any closer. I’m enjoying a celebratory hot buttered rum, and it’s nasty out there!

    Timing is everything, and I couldn’t have done it without  stellar support. You folks run a top-notch operation, and I’ll gladly recommend your business. Thanks for the quick turnaround, the excellent packaging, and great customer support. Here on an isolated island, our merchants know none of the above.

     You guys have a great Thanksgiving. You definitely helped me out!!      You’re welcome in my home, at my table, and better yet, on my boat.

2000 Camaro Z28.  Attn: Craig Stein, thank you very much for taking care of my driveshaft problems, the driveshaft was received yesterday evening and was installed earlier to-day. There were no problems in fitting it, no vibrations as the Camaro ran like new. I gave your card to the shop that installed it as they need driveshafts built from time to time as they do work on drag strip cars. Their website is. Thanks again...Jean Renaud

Just wanted to thank you all for the excellent craftsmanship on my new driveline for my 06 dodge. It fit perfect right out of the package! Now my truck has no more shudder on takeoff and no vibration at all going 70 down the highway. Thanks again!! Will recommend your shop to anyone!!

65 Barracuda  Hi – my shop received the Barracuda driveshaft you manufactured for me and installed it yesterday.  It works great.  The shop was very complimentary on the quality of your workmanship.  The tolerances were apparently quite tight and the shaft fit perfectly.  Thanks, Bob F, Lewiston, Maine


2004 Ram 3500 4x4   Just wanted to let you guys know I am super pleased with my drive shaft. Looks amazing welds were very professional. Fit and finish was perfect lots of spline engadged and still plenty of room to move in and out. Beats the heck out of that 2 piece cluster that was in there. Cannot be more satisfied you guys worked with me even though I was on a tight schedule you made it happen. Thanks again I will definitely recommend you to anyone looking for a one piece for there truck.  Allen McF.



 2010 Ram 3500    Hi Brent I want thank you and Craig, all I can say is Fit/ Workmanship/Quality is all PERFECT thanks. I referred another guy from the cummins forum to buy a shaft from you. He was from Utah and ordered on Mon. I will keep sending guys your way if I can!!!!
thanks Tracy W.





BMW shaft sent to El Salvador

I thought I would wait about a week to give you some feedback on the driveshaft, giving me some time to drive the car and see whether there are any issues.  Pleasantly, everything about the transaction is/was perfect.

First, the item itself was well packed, nicely finished, and looked ready to install.  We pulled the old driveshaft off the car and laid it alongside your rebuilt unit.  Exactly identical, except for yours looking brand new and having U-joints that both actually moved.  On my old driveshaft the rear U-joint was binding, and was the source of the “clink-clink” noise that had turned into a “clack-clack” before becoming a “clunk-clunk”.  Taking our time, working only on jackstands, and not on a lift, we had the new driveshaft installed in a couple of hours, total, from the time we began dropping the exhaust until everything was all buttoned up again.  The car drives smoothly, with no play in the drivetrain, and no unusual noises when setting off from rest or accelerating/decelerating.


  What may be equally impressive is the time in which all this was done, from my first inquiry until we had the new driveshaft in the car.  When I placed my order the item was shipped within hours, headed for my freight forwarder in Miami.  From there they put it on a plane to El Salvador and it went into El Salvador customs on arrival.  While that can often delay a shipment, I was totally pleased that from the time I placed my order to the time we installed the part on the car, only one week had gone by.  Fantastic service, considering this was an export sale/purchase.

   Bottom line, I am completely satisfied with the transaction in terms of product quality and customer service.  Thanks.

Brian McC.


1965 Ford Pickup  Just a quick note to say what a good job you guys did with my drive shaft.
Ordering a drive shaft online for a '65 Ford pickup with a non-standard engine and transmission combination with an e-brake hub that was much older than the rest of the set up was a challenge.
Craig was very helpful throughout the process, explained all the components and correct measurements.
In short, it fit like a glove and installed in about an hour!
thanks again

I just wanted to write and say THANK YOU so much for your help. My parts that I ordered from you for my 2000 Kia Sportage came by 9:45AM and by 1PM the car was completely fixed and running again.

The fact that you were all so wonderful and helpful over the phone made our work so much easier. Now that the car is running I can get back to my college classes and my jobs.

   I just want to convey my utmost appreciation to everyone there at the shop. My 1969 Dodge Super Bee A12 was a real “challenge” and I would not have worked it out without your extensive knowledge and perseverance in problem solving of getting to the root of the initial problem with having a car that is not so “common”. The aluminum driveline that you manufactured for me is of the highest quality not to mention that it fit EXACTLY to the dimensions that were given. Driveline Specialist Of Texas is a top-notch company that has not only earned my respect as a solidly run company with a very high work ethic but also as friend for life as I made the drive from California to shake your hand in person.

  Warmest regards,

I recently purchased a driveshaft for my 2004 Silverado from your firm.  I received it Friday & the moment I saw the packaging I knew I had dealt with a first rate firm. I installed the driveshaft that same day & the fit was perfect. I took it out the next day for a high speed test & all thru the RPM range it was smooth as a baby's rear end (pun intended) It is so smooth that I almost fell asleep while driving. I am totally pleased with the part & the way your firm does business. I will be looking to get you to build me a driveshaft for the front differential shortly. I have already passed on the praise of your firm to my friends.

Just wanted to drop a line about my recent dealings with your company.
I found your add on Goggle while looking up another Drive shaft supplier here in the Northeast. I called and spoke to Jeff, who was very knowledgeable and professional. He immediately understood my situation and suggested the proper remedy.I have a 2000 F250 which I installed a 6 inch lift kit 3 years ago. I finally got most of my driveline vibration addressed but still continued to wear out u joints every 8 -10 months. After making the required measurement per Jiffs request, I ordered the new shaft. The new shaft  was delivered as quoted and on time.  
My truck drives like new!!!

First let me say “you guys rock”!  The quality and fit of your driveshaft is excellent.  It I didn’t know better I would have thought that you guys had my car and did everything in your shop.  Not to mention the quick service and subsequent shipment.  Thanks for everything Jeff!  Your professionalism and knowledge on the phone was great!  I have and will recommend your company in future.  Wish I had known about you when I live and worked in TX.

I got the drive shaft today and it works great. You guys are awesome, thanks again. However, I wish you sold more than drive shaft parts.
Anyway thanks again, I really appreciate you getting the drive shaft to me so quickly.


I just recently purchased a drive shaft for an 2005 dodge 4x4 invoice no#107950 i just wanted to say thank you it fit like a glove i believe it was Brent Crownover that took my order he was the best to talk to on the phone he helped my me out thanks again   Jerry  Minutolo


I just wanted to let you guys know how pleased I am with the aluminum driveshaft you made for me .Very clean show worthy looks and it runs very smooth ,Thank you for your prompt professionalism and workmanship. Derek Bixler

Hi Brent

Installed new shaft.


I thought all that vibration and harmonics was inherent to the diesel.
I,m impressed.

Thanks Muchly
If you need references, a testimony, call me

Thanks Again

PS Does that shaft require oversize permits?

Hello Brent, finally got my car back. The drivshaft is installed and works awesome. Amazing what a little weight savings can do. I noticed a little more understeer but nothing that tapping the brakes won't fix. I will recommend your business to anyone in need of your services. Great customer service and a pleasure dealing with you. I'll get those pinions sent out this week.
Do you have a vice... Lol. Funny guy. 
Take care, Brent.  
Thanks agian,

Received the driveshaft yoke this afternoon; it fits perfect!
Again and with much appreciation, thanks for all your help and going (at least to us) the extra mile in tracking down this uncommon critter.
Until next time.........

 Just to let you know, I got the driveshaft today – it looks as fine as my  old Buick J

Half an hour later it was installed and I took a test drive. 

A long and frustrating story was ended, no hint of vibration to my great relief.

 My old Buick rides as fine as it looks

 Thanks, Erlingur


Just an update. Finally was able to install the aluminum driveshaft you fabricated and in went in without a hitch. The piece looks good, unfortunately after installation you can't really see it the way Mazda covers it up. FYI your unit comes in exactly 1 pound lighter than the OEM carbonfibre one, not bad.

Thanks again



I just wanted to say "Thank you!"  The driveshaft fit perfectly after you all fixed my mistake.  Ya'll went above and beyond anything I expected!  It's nice to talk to someone who really

wants to help and has the knowledge to do so.  A driveshaft is something I don't need very often but when I do, it will come from Driveshaft Specialists!  If any one asks me who to

talk to about a driveshaft, I will definitely tell them about the good folks, great customer service, and excellent products at Driveshaft Specialists.  Thanks again for all your help!


Thank you for the great product!Your customer service is Excellent!Installed shaft and spun the motor to 7800!Wow no issues there !Ps.Can you send me a few drivehaft logo stickers I will highly recommend you !Ben  from NJ.

Hi Brent, it has been several months since you made a 1 piece 5" aluminum driveshaft for my 2003 Dodge Ram 2500 2wd 4dr shortbed pickup. I had to send the driveshaft back and have the yoke shaft shortened about an inch. Just wanted to let you know it has been working great since day one of installation and I couldn't be more pleased to be rid of the trouble and headache of a carrier bearing. My truck is raised 5" in the front and 3" in the rear, but after installing the driveshaft, I only had about 1" of clearance between the carrier bearing crossmember and the new driveshaft. Checked it out and the x-member is light duty and welded at each end to the top outside edge of the frame ( strictly for carrier brng., does not affect frame integrity ). I removed the driveshaft and cut the x-member into with a recip saw and took each half and worked it up and down probably 30 or 40 times and broke each piece of the x-member off right next to the weld and reinstalled ds. I included the info. about the x-member in case it might be helpful to another customer in the future. I  would like to say thanks for a great product and the outstanding service you provided!  Sincerely, David White


Just a short note to let you know that the '87 S-10 Blazer driveshaft that you rebuilt for my vehicle last week runs smoother than ever and am pleased.  I know that good news travels slower than bad but I have meant to report sooner.  Re: invoice 15215.
Regards, and thanks to all Associates,

It's in, it fit perfect and it ran smooth as silk at highway speeds. I'm going to post pics and info for the guys right now. Thanks Brent and thank your crew for me!


    I just wanted to let you know how pleased I am with the drive shaft service I received from you.  Because this car is my daily driver and you had no drive shafts ready to go for my car, you made special arrangements to get my drive shaft rebuilt and back to my the same day.  The rebuilt shaft works perfectly at all speeds and under all acceleration conditions.  Also, you beat the price of everyone else I could find who rebuilds drive shafts, some by several hundred dollars.
Thanks for all your help!  I'd gladly recommend your service to anyone.  Overall a 5-Star experience!!

Just to let you know the shaft is installed and running great.
Will pass your company info whenever I can.
Thanks again.

Installed the D/S this morning, have just 1-1/4" extension from fully collapsed.  Just about perfect.  Took it for a test spin in the desert,  smooth as silk.  Didn't quite get up to 150mph, but I'd bet it would be OK up there. 
When I get an extra $350 we will do the rear one.
Thanks, talk to you again.


Got home bout 11:15, installed the shaft and test drove. I feel as if I have a new truck!! Thanks again for all your staff's efforts and service. I am very pleased with the outcome. Now,'if only I can get another 240,000 miles with this new shaft and the new clutch (first one to be installed), I might start thinking I got my money out of this truck. Lol!!! 

Mark A. Voigt


Sorry I didn't write sooner, (yesterday, about 2 PM), to tell you what you probably already know, you did a "fantastic job" on my shaft! Finally, "a company in the USA" that's "getting it done right"! You guys are doctors! (no shaft jokes)! I'm sorry I didn't resort to you before now, but you will hear from me again, (order(s)). Thanks, great job, David Knight.


You are a standup guy.  It is not often you run across a individual like yourself that takes pride in your work and customers.  That goes a long way!!!   

Thanks, Paul B


Thanks a ton, Driveshaft fit perfectly and was a breeze to install plus I saved a ton of money. Thanks Chris


One tough looking drive shaft !!! It reminds me of the shafts that were fitted behind the early 427 Ford engines. Installed and length is good. Thank you for all the time you spent on me.John

Driveshaft fit perfectly and was a breeze to install plus I saved a ton of money. Thanks Chris


(Suburban driveshaft)Brent just wanted to drop you and your guys a big thank you for the quality job that they did on my new drive shaft. It fixed the vibration problem I was having on my suburban. You did just what was promised  AAAA BIG THANK YOU!!!!  Marty


Brent, have not installed yet. Just wanted to say that you people did a great job on this drive shaft. Thanks again, Ray M. ( 76 VEGA )


<.p4>The following customer had a driveshaft that was dented by UPS when it arrived.  We built a replacement and sent it at no charge.

Mr. M
My name is Brent.
I think it is best that we send you out another driveshaft.
If it was mine I don't think l I would ever be 100% pleased and I want you to be 110% happy.  I will do everything possible to get this on the way today.
Monday would be the extreme.
Do you still have the original carton for the one UPS damaged?
If so I would like for you to send it back in that carton.
When the new driveshaft arrives we will have a pre-paid UPS label to return the damaged one.

I apologize for the inconvenience.
Brent Crownover

(This Brent, I still have the tube the drive shaft came in. Soon as the other one arrives I'll pull it and ship it. Wow talk about costumer service! It looks like you guys take pride in  what you do. I'm the same way. I'm an electrician by trade and help build cars, chassis, headers and other thing for cars. I always get kinda picked on because I want it to be "right" ,to picky I am. Hey, it's got my name on it.  The car I'm currently working on is for a good friend of mine. Could you recommend a shaft for it and give me a round about price.  It is a 79 malibu wagon, it has a 632" Big Chief Headed B.B. Chevy. Dyno'ed a little over 1400 hp with a 200 horse fogger tune-up in it. It will be running a power glide and a fab 9 rear end. I'll be sure to tell him about the service you guy's have given me. Thanks, Jeff M.


Hey Brent,

Just want to let you know I got the driveshaft installed and I must say you do very nice work. Slip yoke travel is about a inch from bottoming out at ride height. I hope to run it this weekend. Thanks again for the nice piece,


Just a short note to thank you for your patience and assistance in identifying and supplying the correct replacement driveshaft for my wife's '99 Volvo V70XC.  I installed it last weekend and the car is running great.  I sent you the old shaft yesterday via UPS - please email me at TKM to confirm receipt and to acknowledge processing of the core deposit. Thanks again, Tom M Lancaster, PA


Mr. Crownover,    I appreciate all your help in finding the right part for my truck. It fit perfectly and solved
my problem. Your customer service is excellent and price was right too. Don't need these
kinds of parts too often but when I do I'll be back. Thanks Mark  Oklahoma


     Brent,   Received d'shaft yesterday- fit perfectly, quality looks excellent. Thanks for the quick response and shipping.  I'll definitely recommend your company to my friends.           Doug M


Thanks Brent.  The driveshaft worked out perfect.  Will keep you in  mind and forward future referrals your way. Don


Hi, My name is Murray R. I am from New Hampshire. I purchased a 2 pieced driveshaft for my 2004 ford F-150 in December. I didn't install it until this past weekend as I waited for the snow to leave. I have a garage under my house but my truck is too high to fit under. I have to tell you that you guys do great QUALITY! work building these driveshafts and the advice on installation via internet is a big help. I just wanted you to know that American companies that do High Quality work like you obviously do are hard to come by and I appreciate doing business with professionals!!! Thanks again and I will do all of the advertising that I can for you guys!!!  Sincerely, Murray R 


The local Fleet Pride driveline shop couldn't make a proper driveshaft despite 3 trips to them to for vibration issues.I phoned your shop,a polite knowledgeable salesperson,the shaft arrives here in New York a few days later. No more vibration issues, thanks. Tony P, Ontario NY


I got the drive shaft about 30 minutes ago I just finished putting it on. Great Job it looks fantastic and fits even better. It got rid of my shaking, clunking and squeaking. Its like having a new truck again. Thanks for everything, Steve Flynn


I just wanted to write and thank you for your fast friendly service I recieved my driveshaft Friday put it in and problem solved  no more vibration I am very satisfied .I would definately recomend your company to my friends.           Thanks    Craig


Jeff, Just a quick note to say thanks for the great driveshaft you built for my son’s 1998 Camaro 3.8L with T5 manual.  It was received on schedule and he said it took him less than 30 minutes to remove the old and install the new driveshaft.  He said it is like driving a different car with the bulletproof aluminum shaft you guys provided.   You made his Christmas. Thanks again, Ron


Hi. My name is Ray M, I just installed my new Aluminum drive shaft for my 1996 Pontiac Firebird, What a difference! I have a lot more torque from the rear! I am very impressed with the Quality of the workmanship! And you made it in one day, and I got it the next day! I will for sure recommend your company to my family and friends! Thanks so much for the excellent service!  Sincerely, Ray M  Upland Ca.


Hi Just wanted to say i got the driveshaft today, bolted right in. Thank you for the quick service. It was a pleasure to do business Thank you Michael 


Hi Brent,
Driveshaft arrived and installed - my problems appear to be solved.
Thanks for the help, especially the extra work on shipping with USPS that saved me paying brokerage fees.

Mr. Murray,
The driveshaft is on the way.  I will send a copy via a different email with tracking info.  The driveshaft did not leave on Friday the 10th as USPS did not pick it up as promised.  So on Monday we went to the Post Office to hand deliver.  Post was closed because of Columbus Day. - Dang!  Went back with it on Tuesday the 14th and they took it. Jeff just tracked it and it does not show anything.  That is what I usually get when I order and track with USPS.  I am sure it will be there soon.

Hey Brent,
Just wanted to let you know that I love the driveshaft so far.  It went right in with no trouble.  However, it's the fuel cell and brake companies keeping my car from moving (both have defects), so I cannot give you a report on how it drives.  I'm leaving for my wedding and honeymoon, so the car will have to sit for about a month.  Thanks for all of your help.Lee


Hi Mr. Crownover,

one year ago I promised to keep you posted concerning the custom made driveshaft you built for my 68 400 Firebird. Some time went by and it runs perfectly! The car´s nearly finished now (still had to get the correct 400 hood + hood tach; the latter two got their paint job today but the car finally will be finished this upcoming week).

Thanks again for your help and could well be that I´m in need of your perfect services again soon: I bought a mint 66 El Camino last year (one of the smaller versions with the standard 283 cci 2bbl engine with powerglide. It still looks very good but I´m afraid I can´t stand the beginning imperfections very long, thus leading me once again into a full restoration... LOL).

I´ve attached a few pics showing your driveshaft after assembly down below in the attachment (perhaps it would have been better not to be caught by the rain before taking pics...).
Enjoy and have a nice weekend!

I bought this 1984 Camaro from a co-worker . It is completely stock and extremely well kept except it had this strange vibration in the shifter that started at 57 MPH , was terrible at 60-65MPH then started to smooth out at 70MPH but was always present after 57MPH. It was so irritating It took all the fun out of driving the car. I received and installed your aluminum drive shaft and transmission yoke today and the vibration is completely gone. I could not be happier. It is smoother than my highest expectations..............................Thanks for all of your technical assistance and for producing a terrific product.................Mark M. B.


Brent,First of all, thanks for the link below – Cool!

 Second, you mentioned on the phone that you rarely hear back when all is well so here’s doin my part for positive feedback…  What a beautiful product!  Great quality, craftsmanship, packaging, service, advice, and very nice paint job.  I will strongly recommend your company to anyone looking for a driveline component.  Thanks for being a source for quality.  There are not enough of you still around.  I hope you never feel tempted to deviate from your formula and that the business rewards you for it.

 Third, I thought you might enjoy this video. If you have good bandwidth, choose the clip in the lower right hand window. These guys are from Cobra Automotive.  This is the kind of thing I hope to do.  My car is a 66 mustang fastback set up for road racing and made to look like a Shelby .  These guys are racing real Shelbys and pushing them hard. This is how to treat a rare $150K vehicle.  They are much beyond me. I hope you like it. Take care, Jeff


Hi Brent and Jeff, 
Received the driveshaft today. Thanks! 
I head for New York tomorrow but I will let you know how the installation goes. 
I appreciate your help and quick delivery on this!

Hi Brent,  Received the drive shaft today and installed it, fits great, and went out and pumped 405 ft lb of torque through it on a squalling peel out and every thing is great. I’m really happy with the beefier yokes and u-joints.  Thanks, Dave  David Fitz  1966 El Camino


Mon nom est Stéphane Lamontagne. Je vous ai acheté un driving shaft dernièrement. Je voulais seulement vous faire part de mes impressions envers celui-ci. Je vous transmet mon entière satisfaction quant à cette pièce. Elle est largement au dessus de mes attentes, merci.

My name is Stephane L. I buy a driveshaft. I would like to tell you that this part is very well and i appreciate it. very thank you your job is perfect.


Just wanted to say thanks.  I ordered a custom driveshaft for my 280Z a week ago and received it today. A superquick turnaround time and it looks outstanding!  Regards,

Hi brent,
Very Nice.........arrived Friday afternoon installed Saturay afternoon Burnin Rubbber late Saturday afternnoon!! LOL Thanks Again


hi brent its nick i got the drive shaft great job you guys are awsome i will recromend you guys to anybody thank you very much


Dear Brent -
I received my new driveshaft on Friday and installed it yesterday.  You guys did a great job.
It fits perfectly and the car now cruises vibration free.  The old driveshaft in the Mustang was rusted and obviously out of balance (I don't know if they even balanced them back in the 1960's).  The driveshaft is a great value for the money and I really appreciate the time you took to get the exact right universal joints for it.  
       I normally purchase my Mustang parts from National Parts Depot, California Mustang or Mid County Mustang catalogs -- you should consider hooking up with these catalogs to offer your products -- because NONE of them have driveshafts available for these old Mustangs and I'll bet there are thousands of customers like myself that would appreciate a new, well made driveshaft for their classic mustang.
 Anyway, thanks again.


I just got my drive shaft today and, It fits great, it went on easier than the old one.
Also, I was wondering if you have a sticker I could put on my back window?
No big deal If You don't...
Matthew R


I sent you a email on short shaft
All is ok and front shaft  in thanks for the shaft and support.
Will use you for my next drive shaft issue and tell others

Hi Brent,
Once again you have gone extra MILES for me regarding my special interest collector cars.  Other than telling others about you and your services and the highest level of my satisfaction, there is only one other thing I can think to do:  I've done a lot of parts research over my life as a resto shop owner / manager and collector and have some sources (such as Collector's Auto Supply) that are well beyond what I would expect you to ever find.  If you are stuck finding a joint OEM part number for a Chrysler product or a resource to get one, I can probably help.  I might be able to do the same for some Ford cars.  I am not a GM fan so I don't have books or references for the Generals cars.   Also in counter discussions of people's cars, if I can help with any other part search, you or your customer are welcome to contact me by email (don't give out my phone, please).
I'm no guru on this stuff, but certainly willing to help in return for the effort you are going to help me.  
The worst case scenario would be if you said "these antiques are driving business down" and you refused to take them in.  Most 1936 and later driveshaft needs are pretty standardized and normal.   And most restorers and modifiers who appreciate the mechanical are desperate for your quality of work.
Thank you and try me if you are stuck and think I can help.
Wayne G


I wanted to drop a thank you for the driveshaft that you all made for my 98 S-10. It fit like a glove; installation took less than ten minutes. Thanks again, if I know of anyone else looking for a driveshaft I will send them your direction.

Hi Brent,
I just want you to know that I received the drive shaft and have installed it. It just slid into place through the safety loop, into the tranny and bolted up to the diff. Perfect.


Hi Brent,
    I appreciate your concern and response.  Great to see I'm working with a customer oriented business.  Regarding the flex-disk, at the time I installed the drive it was NEW.  The driveshaft after I mounted is was about 1/2-3/4 of an inch short.  There is no way the flexdisk can line up perfectly unless the shaft segments move easily since the pilot shaft has to slide into the driveshaft bushing.
   I mounted the bolts, put a litte torque on them and realized the disc had flexed about 1/8-1/4 inch.  As I realized the forward driveshaft segment was not really sliping easily out of the back segment, I used a bar and a hammer to tap it forward to get the slip-section to release.  After a few taps, it did release and the flexdisck straightened up to normal.  I replaced the mounts at the same time.  The old ones were totally shot.  Had a leaky real seal and the tranny fluid basically dissolved them.  Rather like jello when I pulled them out.
   The reason I think it is the driveshaft is because it really is not torque dependent.  For example the vibration sets up if I accelerate slowly or quickly.  Also, if I put the car in neutral from 60 as I slow coming off the interstate and allow the car to slow down naturally, the vibration still happens at the same speed intervals.  The problem I had with the old flexdisk really were torque related.  If I got this wrong please let me know your opinion.
   I may not easily find the time to do this job again.  I hope this does not cause a problem with you in terms of getting a replacement taken care of.  Also, do you suggest I pick up another flexdisk?  I saw what the old one looked like and it was a mess when I started messing with this.  The amount I flexed it was not much more that you could do with your hands when you hold it.
   Again, I really appreciate your help here.  Let me know how to handle this.  I need to look at my calendar for a free weekend to knock this out again.  (Also, not during a blizzard!  We just took a beating with snow up here in DC)
     Bob Z


I have to say, that is one beautiful piece of equipment. Thank you so much for all your help  Ryan


        I want to thank you for your fine service and product. The driveshaft you built for me fit perfect and is strong and dependable. I have had alot of headaches with this project, but the driveshaft wasn't one of them, thanks to you. Thanks again and I will recommend you to everyone.   John T    Russellville, AR 72xxx


Hi Guys
As promised I posted this on the club cobra website
Hi everybody
If you are looking for a driveshaft, I can recommend Driveshaft Specialists of San Antonio. I called them about a custom job: I have a European spec differential from a Ford ScorpioXR4i at the back and a T-5 from a 93 Mustang at the front. They were really helpful over the phone and through email and turned my order around in four days. Several other suppliers had already told me they couldn't do something this non-standard. The driveshaft is top quality, balanced and finished to a high standard. They have a website   John


Dear Jeff

My new driveshaft arrived today and I have to say how impressed I am with your service.  This was a real "custom job" (Ford T5 at the front, European spec XR4 at the back) and it arrived exactly as you said, on time, top quality and fitted right first time. Feel free to quote me. Great Job, especially to Jeff who was so helpful over the phone.  I am going to post on the Cobra Club website and let them know about your great service.  The driveshaft is fitted already and I have attached a couple of photo's if you want to use them on your site
Best Regards


   Dropped the core at the UPS store this morning.

Thanks so much for the great service, I will be
recommending you to others that I know!  Rick


I just ordered a drive shaft the other day,my name is mike n jr. out of san diego.
         It is very seldom that you find a select few that care about what they stand for and sell !.
        Your service you provided me is UNMATCHED as far as i'm concered,

                                           more to come!


Hi, My name is Tom M I spoke with you a month or two ago about a problem with a drive shaft I purchased from you, I was suppose to send it to you because of a  bad vibration in the front shaft, I have been running on my old shaft and my Jeep is vibration free and have forgotten to send the new one back to you. I just wanted to remind you and will be sending it this week. The shaft was for my 1994 Grand Cherokee Limited 5.2 liter I bought it from you sometime in November 2004 put only a 100 miles on it or so, just let me know if you have any questions, thanks again.
Tom M.   (note-driveshaft damaged in shipment, DSI repaired and returned at no charge)

Mr. Crownover,

I received the part on Monday, Quality Transmissions installed it on Tuseday
and I have been riding every since.  Once again, thank you for outstanding
support and superior customer service.

I just wanted to thank you for your support and your donation to our high school Jeep project.  The work you did on the driveshaft of our 87 YJ was fantastic.  My students didn't know you could have driveshafts made longer
I also wanted to update you on the project.  We completed the Chevy 383 stroker conversion (and your shaft is holding up great to it) and got the Jeep back on the road.  We entered 3 car/truck shows this past summer and came out with a second in class finish in one of them thanks in part to your grat work.  We also competed in 7 off-road events coming out with a 3rd, 4th, and 6th place finish being our best showings.  We even got a 12 place finish out of 100 vehicles in the burn-out contest (the kids really loved this) during the 2004 Cruzin Downriver show.  Not once did your shaft fail us.  We can't say enough about your company.  We tell anyone that will listen and even some that won't. 
I also wanted to update you as to the location of the Jeep project.  I have left the Lenawee Career Center and am now Overseeing the Automotive Program at the Sault Area Career Center located in Sault Sainte Marie Michigan.  Yes, it's a huge change from living "down state" to living way, WAY up north, but it's a welcome change.  I like the woods, the trails, and the 4 wheel drive adventures that are offered here that living in the city can not offer.  One major change is the demographic of the students.  The community here is far more into the 4 wheel drive end of the vehicle spectrum than other areas like the sport compact or drag race community.  So the Jeep project lives here, and is far more revered in this community.  We have already scheduled 8 off-road events in the U.S. and Cananda for the 2005 season and the Jeep is entered in the Parade Down Memory Lane during the St. Ignace car show in June.  We are also working on a schedule for several organized off-road trail rides for the coming season with the Jeep running as trail boss.  Currently the schedule stands at 5 runs.
Current upgrades that are in progress include switching tires to swampers on the front and boggers on the rear for the mud bog races, installing locking differentials at both ends and upgrading to 5 point safety harnesses.  When money permits we would like to add a rear bumper with a spare holder to get the spare out of the back seat and convert the suspension to coils through the use of the Black Diamond kit, however, these upgrades are costly and can wait.
We will continue to be a presence in the 4 wheel drive community and will tout your name to all that will hear.  Your logos are proudly displayed on our show board (see attached picture) however we need some stickers for the Jeep.  Could we get a few stickers, if you have them, to show our support?
Thank you again for your support.  If you have any questions, please feel free to contact me.

Sorry I couldn't get back with you earlier.  I installed the driveshaft last Friday and everything works great.  Thanks for the terrific customer service, I'll definitely let everyone know about your business.  I dropped off the core and damaged driveshafts at a UPS store on Monday.
Thanks again

Thank you.  I received the F-150 drive shaft kit, installation was fairly strait forward and easy. I just wanted to thank you for the nice work you do. Just had a few more questions: 
1)  How often (miles) does the drive shaft need to be lubricated?  
2) Can you recommend the type and amount of lubricant that should be used?   
3) Is any other care / maintenance required? 
Thanks again for all your help.

Brent, I just wanted to drop you a line to say thanks for your help in getting a driveshaft for my BMW on the way. It's seldom that you run into a company that has as qualified and hardworking as yours. Too often consumers are quick to criticize and slow to praise. I am an active member of the San Antonio Sports Car Association (SASCA) and have passed along my recommendations of your shop to all the club member through its forums ( Our club website is:  if you are intrested.
Once again, thanks for your help.

Thanks for resizing the Toyota 4Runner driveshaft.  It is installed and works like a charm.  All "booming" and vibration is GONE!
We appreciate the quick turn-around.
