UMI Performance 99-04 Ford Mustang Upper & Lower Rear Control Arms Kit

The rear suspension on your 1999-2004 Mustang can really benefit from an upgrade, especially if you're looking to get a better handle on launches and cornering. This complete kit from UMI Performance includes both adjustable lower and fixed upper rear control arms, designed to replace your stock components with a more robust and performance-oriented setup. They're built to help reduce wheel hop, improve your car's consistency on the track, and generally make the rear end feel more planted.

The lower control arms are constructed from 0.120-inch wall DOM mild steel tubing, a strong material that can handle the stresses of spirited driving. They incorporate a 4130 chrome-moly threaded tube adapter and are fully TIG welded for exceptional strength. For a quiet and comfortable ride, these arms use Energy Suspension polyurethane bushings, which also feature greaseable zerk fittings for easy maintenance. The adjustable nature of the lower arms, thanks to QA1 Teflon-lined spherical rod ends, allows for bind-free operation and precise alignment adjustments. The upper control arms are also made from DOM steel tubing with similar polyurethane bushings and zinc-plated steel sleeves, ensuring a solid and quiet upgrade.

Installation is straightforward as these are direct bolt-on replacements, meaning no drilling is required, and you can use your original hardware. The kit also includes reinforced spring perches and heavy-duty sway bar mounting points, adding further utility to the upgrade. This kit is a well-built option for Mustang owners looking for improved rear suspension performance and durability.
