The torque arm assists in controlling the engine and drivetrain forward and aft twisting motion. The torque arm is inherently soft due to the high compliance rubber bushing design and was built for comfort and not responsiveness or feel. Whiteline’s torque arm mount bushing is built to handle the demands of high torque and power output engines by limiting the amount of movement the engine and drivetrain will place upon the pitch stop. Utilising low compliance bushing technology this eliminates the slop, twisting and shudder found in the OEM rubber bushings allowing for a faster, positive, responsive feel of power delivery on and off the throttle.

Whiteline’s latest technology synthetic elastomer formulation boasts resistance to oil, grease, ozone and weathering.
