The BMR AAU461 Upper A-arms for 1978–1987 GM G-Body applications eliminate upper A-arm deflection to improve steering feel and high-speed stability. These non-adjustable uppers use CNC-machined cross-shafts, stainless bushing retainers, pre-assembled bump stops and new upper ball joints. They add header clearance, help achieve additional positive caster, and refine camber curve for lowered or pro-touring setups.
