UMI Performance's newly renovated Stage 2 handling kit includes everything to upgrade and rebuild the suspension on your classic 1964-1972 GM A-Body. The Stage 2 kit includes upper and lower front A-Arms with 1/2" increase spindle height via ball joints, heavy duty UMI sway bars with new end links and greaseable bushings, UMI monotube gas shocks for all four corners, UMI premium lowering springs, rear tubular upper and lower control arms, replacement rear end housing bushings and heavy duty tubular frame braces. We also include all new Grade 8 hardware with locking nuts to complete the installation. This kit will make any classic cruiser feel like a modern day muscle car! UMI's Stage 2 may be our entry level complete kit but it isn't entry level performance or entry level quality. Perfect for the weekend warrior looking to go for a back road cruise, perhaps hit the drag strip or even an auto-x. As with all UMI Performance products, this kit is 100% Made In USA.
