BMR UTCA007 on-car adjustable upper control arm for 1978–1987 GM G‑body combines a CNC-machined chrome‑moly center adjuster with heavy 1 5/8" DOM tubing to allow pinion-angle tuning and eliminate control arm flex. Two-inch greasable 95‑durometer polyurethane bushings with fluted internals retain lubricant under load, improving driveline alignment and repeatability for street, drag, and road‑race environments.
