What is the benefit of UMI's Roto-Joints?

UMI's Roto-Joints are designed to significantly reduce suspension deflection. This leads to a crisper handling feel, less unwanted wheel hop during acceleration, and makes it easier to adjust your pinion angle for optimal performance.

Can I adjust these control arms without removing them from the car?

Yes, these control arms feature on-car adjustability. UMI's CrMo adjuster allows you to easily make changes to your suspension setup while the arms remain bolted to your Mustang.

Product Details

The Roto-Joints on these UMI Performance adjustable upper control arms are built tough, minimizing suspension deflection for a more responsive feel. If you're looking to firm up the rear end of your 1979-2004 Ford Mustang, whether for street driving, drag strip launches, or carving corners, these arms are a solid choice. They help reduce wheel hop and make tuning your pinion angle much easier.

These arms are designed to be adjusted while still bolted to the car, thanks to UMI's in-house designed and machined CrMo adjuster. This means you can dial in your setup without removing the components. The arms themselves are well-built with thick, CNC laser-cut mounting pads and a combination of TIG and MIG welding for strength. They also feature a durable powder coat finish to resist corrosion.

These are a direct bolt-in replacement for your stock upper control arms and are designed to work with all rear end housings for the specified Mustang models, excluding the 1999-2004 Cobra. Installation is straightforward and typically takes about 1-2 hours with basic hand tools.
