Product Details

UMI Performance is known for making well-built suspension components for classic American cars. If you're working on a 1971-1975 GM H-Body, like your 1975-1980 Oldsmobile Starfire, these non-adjustable upper control arms are a solid option to improve how the rear end handles. They're designed to replace your factory arms directly, helping to reduce wheel hop and give you more consistent traction, whether you're cruising or hitting the drag strip.

These control arms are fabricated from 1.250-inch drawn over mandrel mild steel tubing, which means they're strong and built to last. They're fully TIG welded for maximum strength, and the solid construction gets rid of the flex you might find in the stock arms. UMI also includes greaseable polyurethane bushings with grease fittings and zinc-plated steel sleeves. These bushings help minimize deflection, contributing to better rear stability and improved cornering performance. The installation is a straightforward bolt-on process that uses your original hardware, so no drilling is needed.
