UMI Performance 64-72 GM A-Body Tubular Lower Front A-Arms Corner Max Standard Ball Joint

Built from 1.500-inch USA-made DOM steel tubing, these UMI Performance Corner Max tubular lower front A-arms are designed for serious performance upgrades on 1964-1972 GM A-Body vehicles. They offer a direct bolt-in fit, enhancing steering feel and straight-line stability. The arms are engineered to improve the camber curve and roll center height, which can yield incredible front-end grip for your classic muscle car. This is a coilover-only design, saving weight compared to traditional spring bucket setups.

These A-arms feature a relocated lower ball joint position that can add up to 4 degrees of caster, contributing to better high-speed stability and steering response. The integrated double shear coilover mount is designed to accept standard 1/2-inch rod end shocks and includes spacers for popular models. A double shear sway bar mount is also included, along with an end link that works with UMI's own sway bars (like P/N 4035 and 4067) as well as many factory-style sway bars. The arms come equipped with Delrin bushings for smooth suspension travel and reduced deflection. They are manufactured and raced in Philipsburg, PA, USA.

For an ultimate handling package, consider pairing these A-arms with UMI P/N 4056. The removable lower mounting system allows for spring changes at the track without needing to separate the ball joints, a practical feature for racers. These arms are a solid option for anyone looking to significantly upgrade the front suspension geometry and performance of their 1964-1972 GM A-Body, including models like the Chevrolet Chevelle, Buick Skylark, and Oldsmobile Cutlass.
