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

UMI Performance is known for making well-built suspension components that help you get the most out of your classic American car. If you're looking to improve the handling and steering response on your 1978-1988 G-Body or S10 platform vehicle, these tubular front upper A-arms are a solid option. They're designed to give your car a more precise feel on the road, whether you're cruising, hitting the autocross course, or heading to the drag strip.

What sets these A-arms apart is how they help you dial in your alignment. The ball joint mounting plate is moved to allow for up to six degrees of positive caster without needing a stack of shims. More caster means improved steering feedback and a more stable feel at higher speeds. UMI builds these arms with their own greaseable Delrin bushings, which offer minimal deflection for a tight connection to the road. They also feature strong 4140 CrMo cross shafts, premium ball joints, and polyurethane bump stops, all TIG welded for strength and a clean look. These arms are built on a jig and finished with a durable gloss red or black powder coat to keep them looking good.

These A-arms are a direct bolt-in for factory lower A-arms and spindles, and they're also designed to work with other UMI suspension parts. Installation instructions and recommended alignment specs are included to help you get them set up correctly. They fit a wide range of vehicles, including popular models like the Chevrolet Monte Carlo, Oldsmobile Cutlass Supreme, and GMC Sonoma.
