2WNR Damper System Instructions
General Information before installation
- The dampers are charged with nitrogen gas. The struts with 22 mm shafts are factory charged to 10 bar (150psi) and the aluminum dampers with 16 mm shafts are factory charged to 14 bar (200psi).
- Do not use impact tools to install pin mount top nuts.
- The 8 mm brass hex nut at the top of the damper is the rebound adjuster. PLEASE do not attempt to use this to hold the shaft from turning while installing the first top nut. Install the first top nut onto your mount and snug with a wrench or socket, cinch with a quick jerking motion or hitting with a plastic hammer. This is more than sufficient to secure the shaft to the top mount. Install the second nut and tighten against the first top nut. The use of a tappet wrench (thin wrench) to hold the first top nut will aid in this process. When Installing the rebound adjuster knob onto the 8 mm brass hex nut, make sure that it has clearance from any body component.
The compression adjuster has a range of 15 positions (14 clicks). The compression can be adjusted while the adjuster knob is in the upper position. Push on the Center Release Button to bring the adjuster knob up from the lower (rebound) position to the upper (compression) position. On top of the surface of the adjuster knob, there are arrows pointing for fi rmer and softer settings. Softest position = 0, Stiffest position = 14 Turning the compression adjuster in the clockwise direction (minus) will soften the damper forces in compression Turning the compression adjuster in the counter-clockwise direction (plus) will stiffen the damper forces in compression When installing the shock or strut on the car for the fi rst time, the compression adjuster should be set at 4 clicks from “0”. To do this turn press the center release button to bring the adjuster knob to the upper position then adjust the adjuster knob clockwise until it stops, then back slightly if needed until it settles into a detent. (Caution: once it stops turning DO NOT force it any further) This is the “0” position. From this position turn the knob counter clockwise 4 clicks. The compression is now adjusted.
The MCS 2-Way Non Remote dampers are independently adjustable in rebound (extension) and bump (compression) forces. While the adjuster knob is in the upper position it will adjust the compression forces – while in the lower it will adjust the rebound forces. The release button in the center of the knob is used to release it from the lower position to the upper position.
