UMI’s bolt-in rear coilover bracket kit is a complete mounting solution for your factory axle 1978-1988 GM G-Body. This race-proven 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. This bracket features a multi-position design to allow further fine tuning of ride height and shock location (±¾”). In addition to shock location adjustability, the UMI 3048 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. The kit also features upper reinforcement tabs to distribute the load from the T-bar as well as complete upper and lower hardware. There is no cutting required and your car can be returned to stock at any time. 100% designed, manufactured and raced out of Philipsburg, PA-USA and always US materials.
