Upgrade your rear lower control arms with UMI's heavy-duty tubular setup, now available in Chromoly. Constructed from 1.250" x 0.095" 4130 Chromoly steel, these control arms provide increased strength and reduced weight compared to standard mild steel. CNC machined and fully TIG welded for maximum durability, they feature polyurethane bushings for a smooth ride and on-car adjustability for quick height and alignment changes with just a wrench. Designed to provide additional clearance for large tires and center aftermarket rear ends in the wheel well, the Chromoly construction delivers higher tensile and yield strength, allowing for thinner wall tubing without sacrificing rigidity, giving you a lightweight yet extremely strong performance upgrade.
UMI Chromoly rear lower control arms (1.250" x 0.095" 4130 steel) offer superior strength, reduced weight, on-car adjustability, and smooth ride with polyurethane bushings—perfect for large tires and aftermarket rear ends.
