PRODUCT DESCRIPTION

+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. 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.

Application Guide: Drag Racing – 110lb Spring Drag Racing applications are available with a 110lb spring in conjunction with the ride height options. This package is best utilized on a lightened car. We recommend taking measurements for fitment based on the desired ride height and tire combination.

Street Performance– 150lb Spring Street applications are available with a 150lb spring in conjunction with the ride height options. We recommend taking measurements for fitment based on the desired ride height and tire combination.

AutoX / Road Racing – 225 Spring AutoX / Road Racing applications are available with a 225lb spring in conjunction with the ride height options. We recommend taking measurements for fitment based on the desired ride height and tire combination.

Spanner Wrench & Thrust Bearing Kit: Spanner wrench tool is used to adjust vehicle height while shock stays mounted. This wrench is needed to make height adjustments. The thrust bearing kit is designed to be placed between the spring and the spring seat attached to the shock. This makes for easier adjustments since the spring seat is rotating on a bearing. This kit is recommended for easier adjustments but is not needed to complete the installation. We do not recommend adjusting height on the car without a thrust bearing kit.

Fitment Note: UMI recommends installing the 3054 bracket kit, mocking up the ride height as desired measuring between the upper and lower shock mounting locations, then purchasing the correct length shocks. Rear shocks may not clear all exhaust systems. UMI is not responsible for exhaust clearance issues.

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.
