This kit from UMI Performance is designed for the 1971-1975 GM H-Body and includes tubular rear lower control arms and tubular upper controls. It is a direct bolt-on replacement aimed at reducing wheel hop, improving cornering, and enhancing track consistency for your classic H-Body. Stock control arms can lead to traction loss and poor handling due to bushing deflection and weak stamped material. This kit, made from 1.250” DOM steel tubing and featuring fluted grease-able bushings, is suitable for both weekend cruisers and weekend track enthusiasts. Please note that the 1975 Vega Cosworth and other H-Bodies from 1975 may have a different set-up, so ensure your vehicle has rear upper control arms before purchasing.
