All of the C/K series vehicles use a leaf spring and a 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 the rubber bushings. The rear ends of the springs are attached to the frame with the shackles that allow the springs to change their length while the vehicle is in motion.

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