The Prothane rear track arm bushing set for 1965–1970 Buick Riviera applications replaces worn rubber bushings at the rear track arm with black polyurethane components. These bushings aim to reduce movement and improve alignment control compared with aged mounts while remaining suitable for street use. Confirm fitment to your Riviera's rear track arm before ordering.
