Product Details

If you're working on a 2005-2014 Ford Mustang and want to firm up the rear suspension, these boxed lower control arms from UMI Performance are a solid option. They're built to replace the factory arms, which can flex and deflect, especially under hard acceleration. These UMI arms are designed to minimize wheel hop and help keep your Mustang tracking more consistently, whether you're hitting the drag strip or just want a more planted feel on the street.

What sets these apart is their construction. They're made from oversized, North American boxed steel tubing, measuring 1-1/4” x 2” with a 1/8” wall thickness. This strong, boxed design significantly reduces flex compared to the stock arms. UMI also uses thick-wall bushing holders and greaseable polyurethane bushings, which offer a firmer feel than the factory rubber while still providing a comfortable ride. The fabrication is MIG welded, and they come finished in a gloss powdercoat for durability.

Installation is straightforward. These are a bolt-on part, meaning you can swap them out using the factory hardware without needing to drill or weld anything. It's a job most folks can handle in about an hour.
