UMI Performance's front weight jack system for 1982–1992 GM F-body replaces the factory spring with an adjustable weight jack bucket and a custom 850 lb/in spring for street-oriented handling. It allows up to 2½" of lowering, uses an acme-threaded adjuster with an industry-exclusive thrust bearing for smooth changes, and maintains factory strut clearance for wide tires. Fits UMI and factory K-members; may not fit other aftermarket K-members.
