JRZ RS & RS Pro Shock Absorber System - NSX, 1991-05

The RS & RS Pro shock absorbers have been developed from many years of professional racing experience by JRZ. The RS & RS Pro feature many of the same features as the full featured racing dampers intended for the dual purpose street driven & club racing vehicle.

JRZ RS One & Two Suspension System:
The RS damper allows for external adjustment of rebound and compression (combined in RS One, separately adjustable RS Two) functions of the damper. The RS Two dampers are double adjustable allowing precision adjustment of both low speed compression and rebound. The RS does not utilize a separate canister. The RS has both the rebound and compression adjustments on the damper itself with twelve adjustable settings.

JRZ RS Pro Suspension System:
The next level above the RS is the RS Pro Suspension System. The RS Pro is more similar to the full featured JRZ racing damper than the RS - featuring a mono tube shock absorber and remove reservoirs for increased fluid capacity and heat control featuring separate compression and rebound adjustment. Note: photo above is stock photo not showing NSX lower mount.
