The Prothane front control arm bushing for 1970-1972 GM applications replaces original rubber with a black polyurethane unit to reduce deflection and restore alignment under load. It installs as a direct replacement for front control arms and offers longer-lasting stiffness than worn rubber, resisting oils and contaminants to help preserve handling and steering consistency over time.
