UMI's bolt-in rear coilover kit allows full ride height, spring rate and damping adjustability for your 1978-1988 GM G-Body.

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 ("). The included Viking shock is 19-way adjustable in both compression and rebound and ensures the perfect setting for every application. The 2-" coilover springs are available in 14" 110lb for drag and street use and 12" 150lb for street and handling use. There is no cutting required and your car can be returned to stock if desired. UMI's rear coil over kit also works if your car previously utilized UMI P/N 3010 weld-on relocation brackets. 100% designed, manufactured and raced out of Philipsburg, PA-USA and always US materials.
