UMI Performance 82-92 GM F-Body Front and Rear Weight Jack Kit Street

UMI Performance is known for making well-built suspension components for American muscle cars. This front and rear weight jack kit for your 1982-1992 Chevrolet Camaro or Pontiac Firebird is designed to give you a medium-firm ride that's ready for spirited driving, auto-cross, or road racing. It allows for independent corner weight tuning, which is crucial for getting the most out of your car's handling on the track.

This kit uses strong US Steel for its construction, with jack plates that ride on UMI's exclusive thrust bearings. These bearings help spread the load evenly, making it much easier to adjust your ride height. You can lower your car from stock height down to 2-1/2 inches, with most track testing done at a 2-inch drop. The kit includes 850 lb/in front springs and custom-wound 175 lb/in rear springs, providing a balanced setup for performance driving. Adjustment is straightforward, typically done with a ratchet and a 3/4-inch socket, and the kit maintains factory clearance around the struts, allowing for maximum tire and wheel width.

The rear kit is designed to work with factory rear end housings and Strange Engineering brand rear housings, though minor grinding on the left axle pad is required. The front kit fits both UMI and factory K-members, but may not fit other brands. This kit pairs well with UMI, Viking, or Koni struts and shocks, and can also be used with factory struts and shocks. It's a race-proven system, manufactured and tested right here in the USA.
