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

This package from UMI Performance includes a pair of adjustable tubular front upper A-arms, complete with standard height ball joints and polyurethane bump stops. These arms are built for performance driving, whether you're hitting the track for Pro-Touring, auto-x, or just want a more responsive feel on the street. They are designed to fit a wide range of vehicles from the late 70s through the early 2000s, including popular models like the Chevrolet Monte Carlo, S10, and Buick Regal.

What sets these A-arms apart is their race-quality rod ends, which allow for shim-free camber and caster adjustment. This means you can dial in your alignment precisely without the hassle of stacking shims, leading to improved stability and a more connected steering feel. The ball joint mounting pad has been relocated to further increase caster, and the cross shaft has been shortened for better geometry. They are constructed from strong 0.120-inch wall thickness 1.250-inch diameter DOM tubing with 4130 CrMo cross shafts that are CNC machined and zinc plated. The TIG welding ensures superior strength and a clean appearance. These arms are a direct bolt-in when used with tall spindles and either factory or UMI lower A-arms.

UMI Performance designs, tests, and manufactures these A-arms in Philipsburg, PA, USA. The package includes recommended alignment specifications and detailed installation instructions to help you get the most out of them. A travel-limiting bolt is also compatible with this design.
