Whether you are ordering a brand-new chassis or updating an existing car, every build is completed with precision, consistency, and race-proven design.
Our fully equipped fabrication shop is capable of repairing Harris, Terminator, or any other brand of dirt track chassis. From crash damage to fatigue repairs and updates, we can return your car to safe, straight, race-ready condition — often better than new.
Our in-house parts department stocks a wide range of components needed to assemble, maintain, or upgrade your dirt track car from the frame up. We also have access to parts from many of the industry’s most trusted manufacturers.

At Harris Auto Racing, technical support is not an add-on — it’s part of who we are.
We proudly offer NO-CHARGE tech support to our customers, including setup guidance, troubleshooting, and general race car support during normal business hours.
If you’re considering purchasing a used car, give us a call with the chassis number. We can look up the original build sheet and share all documented information we have on that car. (Note: updates or modifications made after delivery may not be recorded.)
If you’ve purchased a used Harris or Terminator chassis and didn’t receive a setup manual, we can help.
We maintain PDF setup manuals for all years
