The UMI Performance 303233-1-R is a complete tubular upper and lower front A-arm kit engineered to replace weak, stock stamped steel control arms with high-strength DOM tubing construction. Featuring a host of premium, in-house manufactured components, this kit delivers a significant upgrade in handling precision, suspension geometry, and long-term durability. The kit ships fully assembled and ready for a straightforward bolt-on installation, and includes recommended alignment specs along with detailed installation instructions.
The lower A-arms are built from tough tubular DOM steel and equipped with UMI-designed and manufactured greaseable Delrin bushings for precise handling and smooth, bind-free suspension motion. The ball joint mount is angled slightly from stock to accommodate lowered vehicles while also providing additional wheel and tire clearance. Both upper and lower A-arms are jig-built to maintain dimensional accuracy for a consistent, perfect fit every time, and come preloaded with premium ball joints and polyurethane bump stops.
The tubular upper A-arms feature a relocated ball joint mounting pad to increase caster without relying on excessive shims, along with ½" taller upper ball joints for an improved camber curve and better overall front-end geometry. UMI-built billet 4140 CrMo cross shafts are CNC machined and zinc plated for precision and corrosion resistance. Critical weld areas use TIG welding on DOM tubing for superior structural integrity and a clean, finished appearance. This kit affords an 8 lb weight savings over the factory A-arm set.
All components are manufactured with pride in Philipsburg, PA using North American sourced steel. The kit is compatible with factory spindles, drop spindles, factory springs, lowering springs, and coilover kits. A durable glossy red powder coat finish (P/N suffix -R) provides lasting protection and a sharp look under the hood.
