4.84 out of 5 stars 146 Customer Reviews

UMI Performance non-adjustable lower control arms are designed to replace the factory setup. In doing so, they minimize wheel hop and improve cornering, while lowering track ETs and helping track consistency. UMI Performance non-adjustable lower control arms eliminate the flex and bushing deflection found in the factory lower control arms. Their tubular setup is built using 1.500 in. drawn-over mandrel tubing and features TIG-welded construction for the utmost in strength and durability. The rubber OEM bushings are replaced with greasable polyurethane bushings.
