Anti-Windup Bar
The anti-windup bar compensates for rotational torque placed on the rear axle during acceleration and braking by preventing the rear axle and rear spring from twisting (winding up).
The anti-windup bar minimizes noise and vibration issues caused by excessive pinion-to-driveshaft angles during acceleration and braking.

Rear Axle Bumpers
The rear axle bumpers are used to prevent metal-to-metal contact between the rear axle and the frame.

Rear Spring
Semi-elliptic, leaf-type rear springs are used for the rear suspension.
Supplemental air springs are available as part of the optional air suspension system.

Shock Absorbers
The shock absorbers provide the necessary suspension dampening control.

Suspension Fasteners
These fasteners are important parts that can affect the performance of vital components and systems and result in major vehicle damage. New fasteners must be installed if the old fasteners are loosened or removed. New fasteners with the same part number or an equivalent part must be installed if necessary. Do not use a part of lesser quality or substitute design. The specified torque value must be used during assembly to ensure correct part retention.
