The same springs that are offered with our Fox suspension. Quality Eibach springs. These are available to purchase with the coilovers, but just in case you didn't get any here they are!
Available with or without helper springs. The helpers will keep everything aligned and in place if the main springs go loose at full droop. This is dependent on vehicle weight and ride height.
Rates are 550 lb/in front, 375 lb/in rear. Free length is 8", ID is 2.5". Note that these rates or lengths may not be appropriate for all coilover makes.
