The Prothane front control arm bushing for 1970-1972 GM applications replaces aged rubber with a red polyurethane unit featuring a 1.650-inch outer diameter to reduce deflection and restore suspension alignment. It functions as a direct replacement for front control arms, offering firmer handling and resistance to oils and road contaminants to help preserve consistent steering feel over time.
