UMI’s bolt-in rear coilover kit allows full ride height, spring rate and damping adjustability for your 1978-1988 GM G-Body. The upper mount reinforcement is a direct bolt-in and holds a true 2-½” racing coilover with T-Bar. The FEA designed lower bracket bolts in using the standard trailing arm mounting hole as well as an additional reinforcement hole normally used by the standard rear shock. The lower bracket features a multi-position design to allow further fine tuning of ride height and shock location (±¾”). The Viking shock is 19-way adjustable in both compression and rebound and ensures the perfect setting for every application. The 2-½” coilover springs are available in 110lb/in for drag and street use and 150lb/in for street and handling use. In addition to shock location adjustability, the UMI 3064 features three positions of trailing arm location adjustment to fine tune instant center. This adjustment is popular on lowered cars, for drag racing traction, or whenever a geometry change is desired. There is no cutting required and your car can be returned to stock if desired. 100% designed, manufactured and raced out of Philipsburg, PA-USA and always US materials.

Note: Coilover brackets are designed to fit factory rear end housings ONLY and may not fit aftermarket rear ends. Coilover kit P/N 3065 offers more clearance and options for aftermarket rear ends than P/N 3064. Rear shocks may not clear all exhaust tail pipes. UMI is not responsible for exhaust clearance issues.
