UMI’s bolt-in rear coilover bracket kit is a complete mounting solution for your Quick Performance axle in your 1978-1988 GM G-Body. 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 3054 features five positions of trailing arm location adjustment to match the Quick Performance adjustable lower control arm brackets. Minor drilling is required.

Installation & Fitment Notes: UMI recommends installing the 3054 bracket kit, mocking up the ride height as desired, then purchasing the correct length shocks. These brackets are engineered specifically to pair with Quick Performance adjustable lower control arm brackets. The 3054 will also fit on the Quick Performance single hole non-adjustable bracket but will not have the ability to adjust the lower control arms.
