Description

UMI's 4032-1 A-arms are designed for enhanced handling on 1964-1972 GM A-Body vehicles like the Chevelle. Key features include Delrin bushings for precise, bind-free motion and 1/2" taller-than-stock lower ball joints that lower the car by 1/2", add 1/2" of spindle height, and correct bump steer. The A-arms are fabricated from DOM tubing with CNC machined ends, jig-built for accuracy, and TIG welded for strength. They feature an improved ball joint angle for lowered vehicles and increased tire clearance. Includes greaseable, UMI-designed Delrin bushings, polyurethane bump stops, polyurethane spring isolators, and premium 1/2" taller ball joints.
