BMR UTCA006 non-adjustable upper control arm for 1978–1987 GM G‑body replaces flexible stock arms with 1 5/8" DOM steel tubing and 0.120" wall construction to improve launch and cornering consistency. Two-inch greasable, 95‑durometer polyurethane bushings are internally fluted to hold grease and lubricate thrust surfaces, supporting street, drag, and road‑race use with a firmer feel.
