BMR UTCA005 on-car adjustable upper control arm for 1968–1972 GM A‑body combines a chrome‑moly CNC-machined center adjuster with heavy 1 5/8" DOM tubing to provide strength and precise alignment. Two-inch greasable 95‑durometer polyurethane bushings keep lubrication where needed, allowing fine pinion-angle adjustments and improved repeatability for street, drag, and road‑race applications.
