Improve the street and track performance of your GM truck and achieve that precise Pro-Touring feel by combining our popular P/N 3033 upper a-arms with ½” taller premium ball joints. P/N 3033-2 a-arms combine the benefit of additional caster with increased negative camber potential throughout the suspension travel. The relocated ball joint plate offers up to six degrees caster without excessive shimming while the ½” taller ball joint creates up to one additional degree negative camber at full bump travel. Expect improved steering feel courtesy of increased caster and an overall increase in lateral grip due to the camber improvement. Features include greaseable, low deflection UMI designed and manufactured Delrin bushings, CrMo cross shafts, improved header clearance 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 truck, drag truck, autocrosser or Pro-touring machine. Designed and manufactured with pride in Philipsburg, PA - USA.
UMI 3033-2 a-arms boost handling with added caster and camber for better grip and steering feel. Features include tall ball joints, Delrin bushings, CrMo shafts, and durable powder coat—perfect for street, autocross, or Pro-Touring builds.
