UMI????????s tubular panhard bar is a direct replacement for the flimsy stock panhard bar, it adds strength, bushing improvement and rear end adjustment. This is a must for rear end centering after vehicle lowering, as well as clearance for running larger tires. The supplied rod end allows for adjustments off the car to quickly lengthen or shorten the panhard bar to a desired length. The spherical rod end/polyurethane bushing combination eliminates most rear end bind while not sacrificing your ride quality; this is an excellent improvement for your street or drag application. Note: Some 1975 models were built as a 4-link set-up with (2) upper control arms.If your vehicle is a 1975 model please verify your vehicle has a panhard bar. Installation: Easy 30 minute bolt-on installation--no drilling required and uses OEM hardware.
