Tapered leaf springs have three leaves of parabolic taper form. Tapered leaf springs use a front eye and rear compression shackle.

Multileaf springs use a front eye and rear slider. All springs are a two stage-design. All spring and shackle eyes are rubber bushed and non-lubricated.

Spring eyes are fully reamed in order to accept the rubber bushings. The auxiliary spring is a single leaf parabolic taper form and the frame brackets are shaped cams to produce a variable rate.

A polyurethane spring aid and rubber bump stop are attached to the frame. The spring aid and the rubber bump stop hang suspended above the spring center.

Dampening is provided by twin-tube shock absorbers mounted vertically behind the axle. Top and bottom attachments are pin type with rubber insulators. The upper end is attached to a frame crossmember while the lower end is attached to a bracket that mounts below the axle housing.

Shocks are required with the tapered leaf springs and optional with the multileaf springs.

The stabilizer shaft assembly consists of the following components:
