The BMR on-car adjustable polyurethane upper control arm for 2011–2014 S197 Mustangs is designed for 9-inch applications and comes in black hammertone. It provides on-vehicle pinion-angle adjustment, greasable 95‑durometer bushings, and heavy-duty tubular construction to reduce flex and improve repeatability when launching or cornering. Intended as a direct replacement for S197 Mustangs with 9-inch rear setups, it balances articulation with load-bearing capability for consistent handling.
