UMI adjustable upper and lower rear control arm kit for 1971–1975 GM H‑Body vehicles includes both arms with Teflon‑lined spherical rod ends to eliminate rear suspension bind and allow full articulation. The rod ends act as solid bushings for drag applications and reduce bushing deflection. These arms let you fine‑tune pinion angle and rear end position for added tire clearance or aftermarket rear end installs, improving traction and reducing wheel hop. Verify 1975 Vega Cosworth rear hardware before ordering.
