UMI Performance 82-02 GM F-Body Rear Weight Jack System 0lb Race

If you're looking to fine-tune your 1982-1992 Chevrolet Camaro's stance for track days or auto-cross, this rear weight jack system from UMI Performance is a solid option. It lets you adjust your rear ride height precisely, which is crucial for getting the balance just right for corner carving and road racing. The kit replaces your stock rear spring with a system that allows for easy adjustments using common tools.

This system features custom-wound, 200 lb/in race springs made from USA CrSi wire, designed for spirited driving. What really sets it apart is the unique spring perch with a smooth-acting Torrington bearing, making ride height adjustments simple with a 3/4" socket, extension, and ratchet. The heavy-duty jack screw and spring pad are built to last. UMI Performance designs, manufactures, and races these parts in Philipsburg, PA, ensuring they're built tough with a durable red or gloss black powder coat finish.

Installation is straightforward, essentially swapping out the factory spring for the weight jack assembly. Keep in mind that a minor amount of grinding on the left axle pad is required, but instructions are included to guide you through it. This system works with factory rear end housings and also Strange Engineering brand rear housings. It includes an upper poly isolator to help dampen road noise, and it pairs nicely with UMI's 2042UDF shock package.
