Damper Module - Coil Spring Suspension: Damper

The damper assembly is a similar design to the front suspension damper, with a twin tube design with an spring seat attached to the damper body. The lower end of the damper is fitted with a bush and is attached to the lower control arm with a bolt and self-locking nut. The damper functions by restricting the flow of hydraulic fluid through internal galleries within the damper.

The damper rod moves axially within the damper, its movement limited by the flow of fluid through the galleries, providing damping of undulations in the terrain. The damper rod is sealed at its exit point from the damper body to maintain the fluid within the unit and to prevent the ingress of dirt and moisture. The seal also incorporates a wiper to keep the rod clean.

The damper rod is located through a central hole in the top mount. The rod is threaded at its outer end and a self-locking nut secures the top mount to the damper rod.

A spring aid is fitted to the damper rod and prevents the top mount contacting the top of the damper during full suspension compression and assists the suspension tune.
