BMR UTCA005 on-car adjustable upper control arm for 1968–1972 GM A‑body provides heavy tubular construction and a chrome‑moly center adjuster for strength and alignment control. Two-inch greasable 95‑durometer polyurethane bushings with flutes retain grease under load, helping reduce wheel hop and improve repeatability for street, drag, and road‑race driving while maintaining acceptable NVH.
