The rear end of the torque arm extends rearwardly of the rear axle and has a hanger bracket attached thereto. The forward end of a lever arm is supported on a shackle assembly that in turn is mounted on the hanger bracket, and the rear end of the lever arm is mounted on a bushing affixed to the chassis. An air spring is mounted on the lever arm and the air spring and lever arm support major portion of the vehicle weight.
