The UMI Performance rear weight jack and shock kit for 1982-1992 GM F-Body is designed to give ride height adjustability, adjustable rebound damping, and excellent performance. This street kit is suitable for corner carving as well as daily driving with the 175 lb/in spring rate and 40 clicks of rebound adjustment. Built from strong US Steel, the jack plates ride on UMI exclusive thrust bearings which spread the load evenly and help with ease of height adjustment. Ride height adjustment works nicely at factory height through 2-1/2" drop. Most street and track testing was accomplished at 2" drop from stock. Race proven and 100% Made In USA.
