UMI Performance 4033 - 1964-1972 GM A-Body Tubular Front Upper A-Arms, Delrin Bushings

Upgrade your classic A-Body to feel like a modern muscle car with our P/N 4033 tubular upper A-arms. These A-arms feature a relocated ball joint plate that allows for up to six degrees of caster without excessive shimming, resulting in improved steering feedback. The UMI built Delrin bushings provide a precise feel, while the greaseable, low deflection design ensures durability. These track-tested A-arms come with a durable powder coat finish and are designed for improved header clearance. To further enhance performance, consider the P/N 4033-1 with a ½" taller ball joint for an improved camber curve. Our Upper A-Arm hardware kit includes everything needed for easy installation. The A-arms are designed and manufactured in the USA and are compatible with factory or UMI lower A-arms and factory spindles. Please note that they are not recommended for use with cargo coils or above stock height cars.
