Replace the factory’s weak and flexible rubber bushed rear upper control arm on your 1959-1964 Chevrolet B-Body Impala, Biscayne, Bel Air, etc. with our heavy duty adjustable unit!

Our adjustable rear upper control arm allows you to set your pinion angle, provides for serious handling performance and greatly increase the rear end’s fore and aft stability.
