UMI Performance's tubular control arm kit for 1971–1975 GM H-body is a direct bolt-on replacement featuring 1.250" DOM steel tubing and fluted greaseable bushings. It is intended to reduce wheel hop, improve cornering and enhance track consistency compared to weak stamped arms. Note: 1975 Vega Cosworth and some other 1975 H-bodies used a different panhard/torque-arm setup—verify your vehicle has rear upper control arms before ordering.
