This UMI Performance tubular rear control arm kit for 1971–1975 GM H-body replaces stamped components with 1.250" DOM steel tubing and fluted greaseable bushings for improved handling and reduced wheel hop. It's a direct bolt-on upgrade that boosts track consistency and cornering. Important: 1975 Vega Cosworth and some 1975 H-bodies used a different rear setup, so confirm your vehicle has rear upper control arms before purchase.
