Spring rate adjuster (not on XL and only with race spring rates)

We can offer you a spring rate adjuster. The choice for hard or soft springs is an important setting. This stiffness is defined as the spring rate. Intrax now delivers a spring rate adjuster that solves the problem of having to change the springs to change the stiffness and enables an optimum setting under all conditions reducing setup time and purchase costs. By sliding the spring further into the spring rate adjuster a part of the windings is excluded of the spring action and the spring becomes stiffer.
