About Driveshaft Specialist Inc - San Antonio, Texas

We are a family owned business even though incorporated.  The business was established in the late 1950's.  Current ownership started in 2001.

Brent Crownover - President - Sales and Service

Cindy Crownover -Vice President

Billy Fuller - Sales and Service

Jeff Dusek - Sales and Service

Craig Stein - Sales and Service

Driveshaft Specialist Inc. has been manufacturing driveshafts for over 50 years. We were one of the first Driveshaft Specialist shops in South Texas. All we do, everyday, is Driveshaft Service. Nothing else.  We build the finest driveshafts available, one at a time with expert care and workmanship.

Customer Service is not taken for granted, it is the Most Important job we do. We take care of our customers. Customer Satisfaction, Quality of Product and Construction are the ONLY considerations when we build driveshafts.

We do not have any employees in our shop. Employees come in, punch a clock, do what they are told and collect a paycheck. I do not ever want any employees in our shop.  I believe in the term "Associate".  An Associate is someone who is involved with the business operations, they care about the quality of the product manufactured and are PROUD to say, "I Built this Driveshaft".

Our MISSION GOAL is to provide the best possible product at a fair and reasonable price. It is possible that we can build Driveshafts for less, but only if we purchase poor quality offshore products.  We will not do that.  We buy only Top Quality products.  We buy at Warehouse Distributor Net pricing so this allows us to offer Quality Products at a Fair and Competitive price.  You will find a variance of pricing with our competitors, but our goal is not to be the cheapest price you can find… cheap does not mean quality. All of our pricing is calculated to give us a fair margin of return, a reasonable labor rate and cover the cost of doing business.  Please give us the opportunity to service your needs.

I promise you will be pleased with our products.

Sincerely,
Brent Crownover
President

We are going through a transitional stage at this time with our business name. We are evolving towards DRIVESHAFT SPECIALIST INC. of Texas as our primary name.  So if you see Thrash Driveshaft Inc. and Driveshaft Specialist Inc. do not be alarmed. We are one and the same. Thrash Driveshaft is well known in the San Antonio area.  We have had the same Associates from the time of purchase.  We feel that Driveshaft Specialist Inc. more accurately reflects our business operations.
