A Helper spring is used to prevent the Main spring from becoming loose in the spring seat when the suspension is unloaded or at full droop. The Helper spring, unlike the Tender spr ing, has very little spring rate, and therefore has no effect on the suspension characteristics of the vehicle. Up to 2" (50mm) of spring-to-perch gap can be covered with the use of a Helper spring. Show more
