UMI Performance 2015-B Rear Trailing Arm for Chevy/Pontiac

UMI’s heavy duty control arms are direct replacements of the weak, factory stamped rear lower control arms. UMI’s control arms are constructed of 1-1/2” mild steel tubing with CNC machined ends and assembled with polyurethane bushings. These direct bolt-on replacements are designed to minimize wheel hop and improve cornering, while lowering track ETs and helping track consistency. Control arms come complete with polyurethane bushings, grease fittings, zinc-plated steel sleeves and finished in a gloss powder coat.
