UMI adjustable rear upper control arms with greaseable polyurethane bushings are a durable bolt-in upgrade for 1979–2004 Ford Mustang rear ends. They reduce suspension deflection for crisper handling, ease pinion angle tuning, and cut wheel hop. CNC laser-cut mounting pads, CrMo adjusters and a powder coat finish make them long-lasting; installation takes about 1–2 hours and adjusts on-car without removal.
