UMI Performance 78-88 GM G-Body Rear Coilover Bracket Kit Control Arm Relocation Bolt In

If you're working on a 1978-1988 GM G-Body and want to upgrade your rear suspension, this bolt-in coilover bracket kit from UMI Performance is a solid option. It gives you a complete mounting solution for your factory axle, allowing you to install coilovers for improved handling and adjustability. This kit is designed to bolt in using existing trailing arm mounting holes, plus an extra reinforcement hole, meaning no cutting is required and you can always return your car to stock.

What makes this kit stand out is its adjustability. The lower bracket has a multi-position design that lets you fine-tune your ride height and shock location by about three-quarters of an inch. Plus, it offers three positions for trailing arm mounting, which helps you dial in your instant center. This is especially useful if you've lowered your car, are setting it up for drag racing, or just want to change your suspension geometry. The kit also includes upper reinforcement tabs to help distribute load and all the necessary hardware for both upper and lower mounting. It's made from 3/16-inch mild steel, laser cut for precision, and finished with a black powder coat for durability.

When installing, UMI recommends mounting the brackets first, setting your desired ride height, and then selecting the correct length shocks. Keep in mind that rear shock placement might affect exhaust clearance, and this kit is designed for factory rear ends, so aftermarket housings may require a different solution like UMI's P/N 3049 kit. An optional shock tower brace (P/N 3055) is also available to further reinforce your chassis.
