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

When you're looking to seriously improve your classic GM A-Body's handling, this set of UMI Performance Corner Max tubular lower front A-arms is a solid choice. What you get in this package are a pair of well-built tubular A-arms, each fitted with a premium Howe +3/4” tall ball joint. These arms are designed as a direct bolt-in replacement for 1964-1972 GM A-Body vehicles like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark, among many others. They are built from strong 1.500” USA Made DOM steel tubing, making them both lightweight and durable for performance applications.

These aren't just standard A-arms; they're engineered to enhance your car's front-end grip and steering feel. The lower ball joint mounting point is moved forward to allow for up to 4 degrees of additional caster, which significantly improves straight-line stability and steering response. The design also incorporates a double shear coilover mount, accepting standard 1/2” rod end shocks and including spacers for popular models. This coilover-only design helps save weight compared to spring bucket setups. Additionally, a double shear sway bar mount is included, along with an end link that works with many factory-style sway bars. The arms come equipped with Delrin bushings, known for their smooth suspension travel and reduced deflection, contributing to a more precise feel.

For those planning track days or serious performance builds, the removable lower mounting system is a notable feature. It allows for spring or shock changes without needing to separate the ball joints, saving valuable time. When paired with UMI P/N 4056, these A-arms form part of an ultimate handling package. UMI Performance manufactures these arms in Philipsburg, PA, USA, with a focus on race-proven performance.
