Improve performance and make your classic A-Body feel like a modern day muscle car with a complete set of fabricated tubular a-arms from UMI Performance. UMI's P/N 403233-1 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 stock geometry lower a-arms feature tough tubular construction with polyurethane spring isolators for ride comfort 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 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 chromoly 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 ultra tough red or black powder coat finish guarantees your performance parts stay beautiful on your street car, drag car, autocrosser or Pro-Touring machine. The P/N 403233-1 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.
