    UMI Performance 3056-3-B Details

    UMI’s 3056-3 arms are the ultimate in performance and are race proven on the UMI Green Machine. These adjustable upper a-arms are designed to excel in Pro-Touring, road race, auto-x and hot street corner carving. The race quality rod ends provide shim-free camber and caster adjustment along with ultimate smooth travel.

We recommend the 3056 arm for all racing applications. Arm includes 1” taller low friction ball joints for improved camber curve. 100% manufactured, tested and raced out of Philipsburg, PA – USA.
