The patented N10Z Compression Valve automatically and instantaneously adjusts the damping while driving. "The thinking Technology"
The way the N10Z Compression Valve works results in a significant increase in traction and safety compared to conventional systems.

Replaces the OEM valve
Simple installation through replacement
Fine adjustment of compression and rebound via the clicker screws remains possible
Adjusting the high-speed damping on the adjuster is no longer necessary (self-adjusting), the rebound is not affected
Adjustments via the shim setup are still possible
