UMI Performance 3033-B Tubular Front Upper A-Arms Black Powder Coat | GM G-Body S10 S15

The UMI Performance 3033-B tubular front upper A-arms are a direct bolt-in upgrade engineered to eliminate the flex and weakness of factory stamped steel arms. Sold as a pair and finished in a durable gloss black powder coat, these track-tested control arms are designed for street, autocross, drag, and Pro-Touring applications. Designed and manufactured in Philipsburg, PA, USA.
