Your engine torque generates axle wrap and the top link resists axle wrap by pushing and pulling on the chassis. Horizontal loading provides very little downforce on the rear tires and relies mostly on trailing arms for bite.
Torque Arm Chassis Forces
Instead of pushing and pulling generating a horizontal load, the torque arm is designed to translate axle wrap torque into pure vertical loading on the rear tires. This produces way more loading on and keeps the loading constant for better longevity and tire wear. The length adjustment allows you to control precisely the amount of forward bite you want.
Top Link Rear End Travel
A single mounting point above the axles also serves a pivot point for rear end travel. As the car accelerates out of the corner, the rear end drives forward and pivots around the top link taking pulling force and rear bite away from the car.
Torque Arm Rear End Travel
Since the torque arm connects around the bolt circle of the rear end from multiple points, any forward or rearward travel of the rear end pushes the entire torque arm forward and backward with it. Our innovative slider assembly allows the rear end to walk forward without affecting bushing angle, keeping the bushing stack loaded completely vertical and keeping rear bite consistent every lap of the race.
A split arm design along with adjustability to control arm height allows one arm to fit a wide range of chassis options. No matter what chassis you run, you can find the perfect mounting height.
Control precisely the amount of bite you want. The pickup point of the torque arm is the main adjustment point and directly controls front to rear load transfer.
With stackable bushings, including two rates to choose from, you can accurately control torque arm travel. Choose a stiffer setup for faster acting traction or a softer setup for slower and softer acting traction.
