The UMI Performance 5021-B is a tubular single adjustable panhard bar and a direct replacement for the flimsy stock panhard bar on the 1975-1980 GM H-Body. It adds strength, improves the bushing setup and allows rear end adjustment, which makes it a must for recentering the rear end after lowering and for creating clearance to run larger tires. The supplied rod end lets the bar be adjusted off the car to quickly lengthen or shorten it to the desired length. The spherical rod end and polyurethane bushing combination eliminates most rear end bind without sacrificing ride quality, a strong improvement for street or drag use. Installation is an easy 30 minute bolt-on with no drilling required, using the OEM hardware. Note: some 1975 models were built as a 4-link setup with two upper control arms, so if the vehicle is a 1975 model verify that it has a panhard bar before ordering. This part is made in the USA.
