UMI 3056‑3 adjustable upper A‑arms deliver race‑proven geometry with 1" taller low‑friction ball joints for increased camber gain and sharper cornering. Shim‑free rod ends, a relocated ball‑joint pad and CNC machined components give precise adjustment and smooth travel. Designed and tested in Philipsburg, PA, these arms work with factory spindles in most cases and include alignment specs and installation guidance for Pro‑Touring, auto‑x or road‑race builds.
