Description and Operation
Rear Enhanced Suspension
All models use a rear spring suspension system and a
solid rear axle suspension system. The rear axle is
attached to the multi-rear springs by U-bolts. The front
of the spring ends are attached to the frame at the front
hangers through rubber bushings. The rear of the
spring ends are attached to the frame with shackles
that allow the springs to change their length, due to the
spring compressing, while the vehicle is in motion. Two
identical direct dual-action shock absorbers and
hydraulic jounce bumpers provide the ride control. The
jounce bumpers are frame mounted.
Rear Shock Absorber Description
The suspension features a heavy-duty shock absorber
package necessary for off-road conditions. A shock
absorber is a base hydraulic cylinder. The shock is
filled with oil and has a moveable shaft that connects to
a piston inside the shock absorber. Valves inside the
shock absorber offer resistance to oil flow and
consequently inhibit rapid movement of the piston and
shaft. The shocks are angle-mounted between the
frame and the brackets, which are attached to the axle
tubes.
Rear Shock Absorber Cover
Description
The suspension features heavy-duty shock absorber
covers that protect the shock absorber against damage
from severe off road usage while providing full function
of the suspension.
Rear Hydraulic Jounce Bumper
A hydraulic jounce bumper is a basic hydraulic cylinder.
The hydraulic jounce bumper aids the shock absorber
in increased energy absorption and improved
endurance. The jounce bumper is mounted to the frame
above the rear axle.
