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

UMI Performance is known for making well-built suspension components right here in the USA, and this rear weight jack system for your 1982-1992 GM F-Body Camaro or Firebird is a prime example. If you're looking to fine-tune your car's stance and handling, especially for track use like auto-x or road racing, this system lets you easily adjust the rear ride height. It replaces your stock rear spring with a system that offers precise control over how your car sits and handles weight transfer.

This kit features custom-wound, 200 lb/in race springs made from USA CrSi wire, which is a solid choice for corner carving and performance driving. The real trick here is the UMI-designed spring perch with a Torrington bearing. This bearing makes adjusting the ride height smooth and simple, even under load, using just a 3/4" socket and extension. You can make these changes right through the existing hole in your axle. The system also includes an upper poly isolator to help dampen road noise, giving you a bit more comfort on the street. Installation is straightforward, essentially a bolt-in swap for your factory spring, though it does require minor grinding on the left axle pad as detailed in the included instructions.

This weight jack system is designed to work with factory rear end housings and also Strange Engineering brand rear housings. For the best results on the track, UMI recommends pairing this with their 2042UDF shock package. The system comes finished in UMI's signature tough red or gloss black powder coat.
