Rebound Adjustment Mechanism

Proprietary adjustment mechanism to manipulate rebound damping forces.

Main Piston Assembly

Generates overall valving range. Valving can be manipulated by changing the non-preloaded shim stack configuration on the compression and rebound sides of the piston.

Support Piston

Provides additional lateral support on piston end of shaft assembly.

Shaft Guide

Creates additional lateral support on shaft-end side of shaft assembly.


Also known as piston rod. Responsible for displacing fluid in the damper body to be controlled by piston assembly and adjustment mechanism. We utilize 22mm diameter shafts for strut applications and 16mm diameter for shock applications on the 1WNR damper system.

Rebound Adjuster Knob

Connected to the internal rebound adjustment mechanism and allows user to change rebound damping forces easily.

Compression Adjuster Knob

Connected to the internal compression adjustment mechanism. Allows user to change compression damping forces easily.

Compression Main Piston Assembly

Contains proprietary internal adjustment mechanism for compression damping forces.

Dividing Piston

Separates the gas cavity from the oil cavity.

Schrader Valve

Make gas pressure changes easily with a shock tool.
