UMI has raised the  bar. Our host of ultra-premium features come together in one package to provide  your ride with unmatched precision, performance, durability and quality. UMI’s  P/N 383233-2 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 and are loaded with ½” taller upper ball joints to improve  camber performance. Both upper and lower a-arms are jig built to maintain  accuracy for a perfect fit every time and 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 383233-2  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.
