              DirtWorks to soley focus on fabrication!

Effective immediately, Shockworx (located in Trenton, MO) has acquired the suspension service, modification, and tuning department of Dirtworks Motorsports!


Shockworx is a new upstart company to the ATV industry, but it's owned and operated by Bart Thomas, who is no stranger to the race track. Bart has been offering a very successful ATV engine building and race prep program in the Midwest for years, and also has been competing himself, so he fully understands the on-track demands placed on a race quad. We've been needing to focus more on our fabrication side, and Bart had been wanting to increase his services offered to the race crowd, so the transaction just seemed to make perfect sense.



#1 Effective immediately, Shockworx/Bart Thomas is your new GO-TO guy for your suspension service and tuning needs. He owns all of our equipment, tuning resources , inventory, and has been spending ample time in training here, so there is no reason that he can't offer the same level of suspension services that we have for years.


#2 DIRTWORKS MOTORSPORTS IS NOT CLOSING!!! Actually,it's just the opposite. We are simply going to focus more on our fabrication department, and attempt to reduce the lead time that we have always had on the parts that we produce in house. And, hopefully be able to finish up development on some new products that we have never had time to complete before.

#4 We owe a huge THANK YOU to all of the customers in the past that have chosen Dirtworks to be there suspension tuning company. Most racers would trust someone holding there children before they trust someone holding there shocks! So anytime we have had a customer trust us with their suspension, that is something that we don't take lightly.

Highlighted Product - Dual Battery Setups

We are proud to announce the release of our new 24 volt battery kit for Honda TRX450R and KTM 450/525XC models.  These are complete systems including all components except battery, necessary to provide fast 24 volt starting power for holeshots and restarts with a hot engine.  24 volt power is provided directly to the starter, and not to the remaining electrical system.  Months of testing have insured that these systems will hold up to the rigors of XC racing.


The kits come with complete instructions and step by step photos so that anyone can install at home in their garage.  Battery boxes are water jet cut from 5052 aluminum and tig welded for strength.  Custom cables are included with copper lugs and plastic jacketing specific to each model.  These kits take the mystery out of 24 Volt starting systems, and anyone can gain the same advantage of a factory race team.
