UMI Performance 78-88 G-Body S10 Tubular Front Upper A-Arms Adjustable No Ball Joints

When you're looking to dial in your suspension for serious performance driving, what you get in this package are UMI Performance's adjustable tubular front upper A-arms. These aren't just any A-arms; they're built for demanding use like Pro-Touring, road racing, and auto-cross, offering a significant upgrade over stock components. You'll receive a pair of well-built tubular A-arms, complete with polyurethane bump stops and a travel-limiting bolt provision. Importantly, these arms do not include ball joints, as they are designed to be used with specific tall spindle setups and separate ball joints, which you'll need to source elsewhere.

What sets these UMI A-arms apart is their focus on adjustability and improved geometry. They feature race-quality rod ends that allow for shim-free camber and caster adjustments, making alignment much simpler and more precise. The ball joint mounting pad is relocated to increase caster, which helps improve stability and steering feel, especially at higher speeds. This design also shortens the distance between the cross shaft and the ball joint. The arms themselves are constructed from strong 1.250-inch diameter DOM tubing with a 0.120-inch wall thickness, and the cross shafts are made from 4130 CrMo steel, CNC machined and zinc plated for durability. They are TIG welded for superior strength and a clean appearance, and the laser-cut ball joint pad ensures accuracy. These arms are designed to bolt directly to factory or UMI lower A-arms and factory spindles when used with tall ball joints.

This set is designed to fit a wide range of vehicles, including popular models like the Chevrolet Monte Carlo, S10, and Buick Regal, among many others from the late 70s through the early 2000s. UMI Performance includes recommended alignment specifications and detailed installation instructions with the package to help guide you through the process. Remember, these A-arms require the use of tall spindles and a separate ball joint; they are not designed for use with standard height ball joints on standard spindles.
