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

If you're looking to sharpen up the handling on your 1978-1988 GM G-Body or S10 platform vehicle, these tubular front upper A-arms from UMI Performance are a solid choice. They're designed to improve steering feel and increase cornering grip by adjusting your suspension's caster and camber geometry. This is a popular upgrade for street trucks, autocrossers, and Pro-Touring builds where precise control is key.

These A-arms feature a relocated ball joint mount that allows for up to six degrees of additional caster without needing excessive shims. Combined with the included 1/2-inch taller ball joints, you gain up to an extra degree of negative camber at full suspension compression. This updated geometry results in a more connected steering feel and improved lateral grip through turns. UMI builds these arms with greaseable, low-deflection Delrin bushings and strong CrMo cross shafts. They also offer improved header clearance and come with polyurethane bump stops to help manage suspension travel. The robust tubular design is TIG welded for strength and finished with a durable gloss red powder coat.

This kit includes the A-arms, a hardware kit with Grade 10.9 bolts, washers, and nylock nuts, and detailed installation instructions with recommended alignment specs. They are designed as a direct bolt-in replacement for your factory upper A-arms and are compatible with factory or UMI lower A-arms and spindles.
