UMI Performance 05-10 Ford Mustang Adjustable Upper Control Arm

If you're looking to get more out of your 2005-2014 Ford Mustang, especially when it comes to launching and handling, this adjustable upper control arm from UMI Performance is a solid option. It replaces the factory stamped control arm, which can flex and deflect under hard loads, leading to wheel hop and unpredictable handling. This upgraded arm is designed to reduce that flex, giving you better control and improved traction, whether you're hitting the drag strip or just want a more stable feel on the street.

This control arm is built tough, featuring a 0.250-inch thick steel mounting bracket that's CNC machined for a precise fit. It uses a QA1 Chrome Moly spherical rod end with a self-lubricating race, allowing your suspension to articulate freely without binding, which is crucial for high-performance handling. The adjuster itself is made from heat-treated 4140 Chrome Moly, and the tube adapter is also Chrome Moly to ensure thread durability. Plus, you can make on-car adjustments with just a wrench to fine-tune your pinion angle for suspension setup or correction, especially if your Mustang has been lowered. It’s a 100% bolt-on installation, reusing factory hardware.

This kit also includes a spacer kit (Part #1058) to address a common issue on the factory rear upper control arm mount. Ford uses a 14mm bolt but the chassis mount hole is 16mm, creating slop that can cause noise and clunks. The stepped spacers reduce the hole size to 14mm, ensuring a tighter fit and eliminating that unwanted movement. This control arm is available in a durable black or red powder coat finish.
