1964-1972 Chevelle UMI Tubular Front Upper Control Arms, Black 4033-B

Improve handling and make your classic 1964-1972 Chevelle feel like a modern day muscle car by installing our P/N 4033 tubular upper a-arms. The relocated ball joint plate on these a-arms permits up to six degrees 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, chromoly 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 car, drag car, autocrosser or Pro-touring machine. For even more performance, check out the P/N 4033-1 which adds the benefit of a 1/2 inch taller ball joint for an improved camber curve and flatter contact patch.
