Accurately measuring dynamic wheel loads on dirt late models and modifieds requires duplicating the forces generated on the track, as accurately as possible. A substantial amount of these forces are produced through acceleration. This system applies acceleration torque through the rear end housing effectively loading the lift arm or pull bar which creates chassis lift. The leverage from this lift simultaneously loads the rear tires while the forward pull of the acceleration cylinder loads the trailing arms, accurately simulating forward drive on the track. This package includes
Summary: With this system you can load the rear end housing, trailing arms, bird cages, etc., and travel the front end with steer in the wheels while reading all the measurements listed below. No engineering degree required. We teach you how to do everything.
