Helper Spring, Black, 3.000 in. Inside Diameter, 4.840 in. Length, 23 lbs./in. Rate, Each

As part of their ERS system, Eibach's ERS helper springs prevent the main spring from loosening in the spring seat when your suspension is unloaded or at full droop. They have very little spring rate, and therefore no effect on suspension characteristics. Up to 2 in. (50mm) of spring-to-perch gap can be covered with the use of a helper spring. Order the length and spring rate preferred for your application.
