Pistonrod diameter upgrade

Improve your McPherson damper by upgrading to a larger diameter shaft. The larger shaft has a more rigid and stronger strut construction which benefits when side loads are applied. Side loads are applied when cornering, or braking.



With the larger shaft your JRZ has a large oil displacement so the damper creates damping forces at the smallest movements of the suspension.

The combination of the larger shaft and the use of nitrogen pressure results in a lifting force created by the damper. This lifting force is available through the whole stroke of the damper and works together with the spring, the lifting force is not a spring rate, but gives the car platform. Upgrading to a larger piston rod benefits the lifting force.
