QA1 Mustang Race Control Arms combine performance, durability, and style, making them the perfect upgrade for any Mustang. Built with lightweight, high-strength materials and a sleek design, these control arms not only improve your vehicle’s handling but also enhance its overall appearance.
On-The-Car Adjustability
With QA1’s exclusive eccentric adjustment sleeve, you can fine-tune your camber and make up to a 1/2″ track width adjustment without needing to remove the control arms from the car— a feature that sets them apart from the competition.
Forged Ball Joint Housings
The forged ball joint housings deliver outstanding strength and reliability. Featuring a low-friction, rebuildable, and greaseable design, these ball joints ensure smooth operation and easy maintenance, keeping your Mustang performing at its best.
Ultra-Low-Friction Composite Bushings
QA1’s ultra-low-friction composite bushings offer enhanced stability and control with bind-free movement. These bushings are far more durable than traditional rubber options, providing a longer lifespan and resistance to wear. Plus, the greaseable design ensures they continue performing optimally over time.
