Upgrade your rear lower control arms with UMI's heavy-duty tubular set up. Constructed of DOM mild steel tubing, CNC machined, and fully TIG welded for maximum durability. These control arms come with polyurethane bushings for a smooth ride and feature on-car adjustability for quick adjustments with just a turn of a wrench. These control arms are designed to provide additional clearance for large tires and center aftermarket rear ends in the wheel well. The Chrome Moly version uses 1.250" x 0.095" 4130 Chrome Moly steel for increased strength and reduced weight. This construction adds higher tensile and yield strength compared to mild steel, allowing for the use of thinner wall tubing for extreme lightweight and strength.
