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

UMI Performance is known for building well-made suspension components that hold up to hard use, and these adjustable upper A-arms are a prime example. If you're looking to dial in your Pro-Touring build, road racer, or just want a more stable and responsive feel on the street, these arms are designed to help you achieve that. They are built for a range of popular vehicles, including models like the Chevrolet Monte Carlo, S10, and Oldsmobile Cutlass Supreme, offering a significant upgrade over stock components.

What sets these A-arms apart is their race-quality rod ends, which allow for shim-free camber and caster adjustments. This means you can fine-tune your alignment precisely without the hassle of stacking shims, which can sometimes lead to less consistent results. UMI has also relocated the ball joint pad to increase caster, which is key for improving straight-line stability and enhancing steering feel. The cross shaft has been shortened, and the ball joint pad is laser cut for a precise fit. These arms are designed to work with tall spindles, which is a common setup for performance builds, and they come with polyurethane bump stops and travel-limiting bolt compatibility.

Constructed from 1.250-inch diameter DOM tubing with a 0.120-inch wall thickness, these A-arms are built to be strong. The cross shafts are made from 4130 CrMo steel, CNC machined, and zinc plated for corrosion resistance. They are TIG welded throughout for superior strength and a clean appearance. UMI includes recommended alignment specifications and detailed installation instructions to guide you through the process. These are designed as a direct bolt-in replacement when used with compatible lower A-arms and tall spindles, making them a solid option for serious performance upgrades.
