For the rear suspension components, refer to Rear Suspension Components .

All P model vehicles use a leaf spring and solid rear axle suspension system.

The rear axle assembly is attached to the multi-leaf springs by the U-bolts. The front ends of the springs are attached to the frame at the front hangers through rubber bushings. The rear ends of the springs are attached to the frame with shackles that allow the springs to change position while the vehicle is in motion.

The ride control is provided by two identical, direct, double-acting, shock absorbers that are angle-mounted between the frame and the brackets, and are attached to the axle tubes.
