Used by champion drivers! The “Three Stage” torque link provides adjustable progressive action for ultimate torque control and traction. Torque is absorbed by the coil spring to provide initial forward bite. As engine torque increases, the poly bushings engage to increase torque to the rear tires. Engagement point of the poly bushings can be adjusted independently from the coil spring to allow for changing track conditions. Due to its unique twin shaft design, the engine side and brake side operate independently. This allows corner entry & exit to be tuned separately. Bushing/spring pre-load is always maintained. Also the brake bushing works more effectively because it’s not loaded with engine spring pre-load. The car turns better during deceleration as a result.
