The components of the rear suspension use a leaf spring and solid rear axle suspension system.

The front ends of the springs are attached to the frame at the hangers, through rubber bushings. The rear ends of the leaf springs are connected to the frame with shackle assemblies. The shackle assemblies allow the leaf springs to change positions in response to different road and payload conditions. The leaf springs are connected to the rear axle with an anchor plate, the lower plate, the U-bolts, and the attaching hardware. The shock absorbers are attached to the rear axle and the frame. The shock absorbers dampen or smooth road inputs.

An optional spring steel stabilizer shaft helps minimize body roll and is available as part of the sport suspension package. The stabilizer shaft is connected to the rear axle and the frame with the rubber insulators, the clamps, and the link assemblies.
