Chevelle based chassis

The chassis was designed to be strong, safer, and easier to drive and setup than traditional chassis. Using new computer technology the guess work has been taken out of the front and rear suspensions. The design of the car is different than a lot of cars out there and we hope to bring a new perspective to dirt modified racing.

Ultimate RaceCars builds new cars and will service and repair any brand chassis.
