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

If you're looking to dial in your suspension for serious performance driving, like Pro-Touring, road racing, or auto-cross, these adjustable upper A-arms from UMI Performance are built for the job. They are designed to fit a wide range of popular vehicles from the late 70s through the early 2000s, including models like the Chevrolet Monte Carlo, S10 pickup, and Buick Regal. These arms are race-proven, even featured on UMI's own 'Green Machine,' and are engineered to give you precise control over your alignment settings.

What sets these A-arms apart is the use of race-quality rod ends, which allow for shim-free camber and caster adjustments. This means you can fine-tune your alignment without the guesswork and potential for error that shims can introduce. The ball joint pad has been relocated and is 1 inch taller than stock, which helps increase caster. More caster means improved stability at higher speeds and a more responsive steering feel, especially important when you're pushing the limits. The construction uses 1.250-inch diameter DOM tubing with 0.120-inch wall thickness and 4130 CrMo cross shafts that are CNC machined and zinc plated for strength and corrosion resistance. They are TIG welded for a solid, clean build.

This package includes the upper A-arms with the taller ball joints, polyurethane bump stops, and travel-limiting bolts. You'll also find recommended alignment specifications and detailed installation instructions included to help you get them fitted correctly. These are designed as a direct bolt-in when used with factory or UMI lower A-arms and factory spindles, making the installation process more straightforward.
