You take pride in your ride whether it's slammed to the ground or infused with a ton of power. Don't settle for those flimsy, stock a-arms. Upgrade to UMI's fabricated tubular a-arms and improve your vehicles street and track performance. UMI’s P/N 383233-1 upper and lower a-arm kit replaces the worn out, stock stamped a-arms with high-strength tubular construction and a host of premium features. The lower a-arms feature tough tubular construction and greaseable Delrin bushings for precise handling and smooth suspension motion. We build the Delrin bushings in-house to ensure the ultimate in quality and smooth suspension action. The ball joint mount is angled slightly from stock to permit usage with lowered vehicles and the design offers additional wheel and tire clearance. The tubular upper a-arms are assembled with smooth operating, low deflection UMI designed and manufactured Delrin bushings as well as UMI-built billet CrMo cross shafts. They feature a relocated mounting pad to increase caster without excessive shims. Both upper and lower a-arms are jig built to maintain accuracy for a perfect fit every time and both come preloaded with premium ball joints. Critical areas are TIG welded for superior strength and a clean look. UMI’s extensive testing on the street, drag strip and skid pad ensures a quality product able to with stand all types of conditions. The P/N 383233-1 a-arm kit will work with factory springs, lowering springs and coil over kits such as the popular QA1 coil over set up. For the best handling and tire life from the UMI designed a-arms, included with each kit are recommended alignment specs along with detailed installation instructions. UMI Performance a-arm kit P/N 303233-1 is shipped fully assembled and ready for installation. Manufactured with pride in Philipsburg, PA – USA.
