UMI Performance 78-88 G-Body S10 Tubular Front Upper A-Arms Adjustable

UMI Performance is known for making well-built suspension components that perform on the street and the track. These adjustable upper A-arms are a prime example, designed to give your 1978-1988 G-Body or S10 vehicle improved handling and steering feel. Whether you're building a Pro-Touring machine, hitting the auto-x course, or just want a more responsive feel on your hot street car, these arms are engineered to make a difference.

What sets these arms apart is the race-quality rod ends that allow for shim-free camber and caster adjustment, making alignment much simpler. They also feature a relocated ball joint pad to increase caster, which helps with stability and steering feedback without needing excessive shims. The cross shaft is shortened, and the ball joint is set 1/2 inch taller than stock to improve the camber curve during suspension travel. These arms are constructed from 1.250-inch diameter DOM tubing with 0.120-inch wall thickness, and the cross shafts are made from CNC-machined 4130 CrMo steel. They are TIG welded for strength and a clean appearance, and include polyurethane bump stops.

This package is designed as a direct bolt-in for factory or UMI lower A-arms and works with factory spindles. UMI includes recommended alignment specs and detailed installation instructions to help you get the most out of these arms. They are manufactured and tested in Philipsburg, PA, USA, ensuring a well-made product ready for demanding use.
