Progress Competition Series Coil Over Suspension Systems feature dual-rate rear springs. This arrangement uses higher spring rate coils and lighter "tender" springs on the rear struts. The tender springs maintain preload on the spring assembly when the suspension is at full droop, making the system trouble-free. These sytems are Bolt-In, meaning that the systme installs without vehicle modifications. Shorter Struts for lower ride heights, improves ride quality and traction, Polyurathane "Short Stops" allow additional wheel travel (New strut top bushings and spring isolators are included). A Take-Aprt design allows for easy revalving. All this and Threaded Spring Pearches to help adjust 1"-4" between Ride Heights.
