UMI Performance 79-04 Ford Mustang Adjustable Upper Control Arms- Poly Bushings

If you're looking to dial in the rear suspension on your 1979-2004 Ford Mustang, especially for street, strip, or track use, these adjustable upper control arms from UMI Performance are a solid choice. They replace your stock arms and give you the ability to fine-tune your pinion angle, which is crucial for everything from reducing wheel hop to optimizing power delivery under acceleration.

What sets these apart is the on-car adjustability, meaning you can make changes without having to remove the arms from your car, saving you time and hassle. They feature greaseable polyurethane bushings that help minimize suspension deflection for crisper handling, and the arms themselves are well-built with thick, laser-cut mounting pads and a mix of TIG and MIG welding. The CrMo threaded adjusters add strength where it counts, and the durable powder coat finish helps them stand up to the elements.

These are designed as a direct bolt-in replacement, making installation straightforward with basic hand tools. Getting the pinion angle just right can make a noticeable difference in how your Mustang launches and handles, and these arms give you that control.
