The BMR AAU462 Upper A-arms for 1978–1987 GM G-Body applications eliminate upper A-arm deflection while accommodating a 0.5-inch tall ball joint. These uppers feature CNC-machined, nickel-plated dual-offset cross-shafts, stainless retainers, pre-assembled bump stops and greaseable Delrin bushings for a firmer, quieter feel. Designed for street, drag, and pro-touring use, they free up header clearance for larger primaries.
