The Chassisworks rear coil-over conversion uses a true coil-over shock designed specifically for the damping and travel requirements of the 1979 to 2004 Mustang and other Fox chassis vehicles. The system utilizes OEM mounting locations and can be used with direct-fit FAB9™ or factory rearend housings. An adjustable lower shock mount is available for both FAB9™ and factory housings. Each end of the shock features a spherical bearing that enables misalignment as needed and avoids unpredictable, untunable bushing deflection. The unique, upper spherical mount is a VariShock exclusive. Extended-stem-style configuration lowers the upper spring seat for additional tire clearance. The stem features an easily accessible zerk fitting to inject grease directly onto the bearing contact surfaces. Shocks are available with 16-position, single- or double-adjustable damping. Kits include 6”-travel coil-over shocks, springs in a choice of rates ranging from 80 to 450 lb, and a VariShock spanner wrench. Spring-seat thrust bearings are available to ease preload adjustments. True stock location bolt in coilover shock, Double adjustable Billet body, Smooth consistent valving.
