Shock Assembly: Operation

The shock absorber assembly cushions the ride of the vehicle, controlling vibration, and jounce and rebound of the suspension.

The coil spring controls ride quality and maintains proper ride height.

The spring isolators isolate the coil spring at the top and bottom from coming into metal-to-metal contact with the upper mounting bracket and shock absorber.

The jounce bumper and cup limit suspension travel and metal-to-metal contact under full jounce condition.

The shock absorber dampens jounce and rebound motions of the coil spring and suspension.
