These springs are designed so that the lower end sets on the coil-over shock and the upper end sets in the original spring bucket in the frame. This allows for the use of a longer and lighter spring for more stored energy, offering increased weight transfer. Greater durability is also achieved by locating the spring pressure in the frame and not on a single stud. The threaded aluminum body allows ride height adjustment and boasts an easy bolt-in installation. The system includes aluminum body coil-over shocks, specially designed conical springs and all mounting hardware. Note: Specify spring rate (350, 400, 450, 500 or 550#) when ordering kit.

Note Kit Includes: CPSPAN-K Spanner Wrench & Thrust Bearing Kit (necessary when installing coil over system).
