Design ensures steep increase of damping forces in compression stroke for piston rod velocities exceeding 1,5 m/s. Features adjustable switching point, damping force gain and rate. Can be added to base valve, piston valve or both valves.
Ensures additional protection of other suspensions components at high compression impacts (bad roads) by dissipating excess of impact energy inside the damper. Contributes to improved vehicle handling in off-road conditions.
