Improve handling and fulfill your G-Body's built-in performance potential by installing our P/N 3033-1 tubular upper a-arms. The relocated ball joint plate on these a-arms permits up to six degrees of positive caster without excessive shimming. Expect improved steering feedback courtesy of increased caster and a precise feel due to the UMI built Delrin bushings. Features include greaseable, low deflection UMI designed and manufactured Delrin bushings, CrMo cross shafts, premium ball joints and polyurethane bump stops. These track-tested, jig built DOM a-arms are supplied with a durable gloss red or black powder coat finish which guarantees your performance parts stay beautiful on your street car, drag car, autocrosser or Pro-touring machine. For even more performance, check out the P/N 3033-2 which adds the benefit of a ½” taller ball joint for an improved camber curve and flatter contact patch.
Upgrade your G-body/S10 with UMI 3033 tubular upper a-arms for added caster, better camber curve, and sharper steering. Includes Delrin bushings, chromoly shafts, and premium ball joints. Track tested and proven.
