Our tubular on-car adjustable panhard bar replaces the flimsy factory panhard bar while adding increased strength 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 CNC machined double adjuster features left and right hand threads for quick and easy on-car adjustments by simply loosening two jam nuts. 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. As well as easy adjustments, our heavy duty panhard bar also increases rear stability, controls side movement and body flex. 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.
