Product Overview QA1's Mustang race control arms are the perfect combination of performance and style, offering lightweight, durable construction and a clean, sleek design that will enhance the look of your Mustang. On-The-Car Adjustability QA1's unique eccentric adjustment sleeve allows for precise tuning of camber and up-to a 1/2 of track width adjustment without removing from the car, a feature not found in other control arms. Forged Ball Joint Housings A unique feature of the QA1 control arm is the forged ball joint housing. This provides exceptional reliability, strength, and durability. The low-friction ball joint ensures smooth operation, and the rebuildable, lightweight, and greaseable design makes maintenance a breeze. Ultra-Low-Friction Composite Bushings QA1's ultra-low-friction composite bushings are stiffer and provide bind-free movement, providing enhanced stability and control. They also allow for freer movement, resulting in a more responsive ride. Additionally, these bushings are much more durable than rubber bushings, making them highly resistant to wear and tear. Finally, composite bushings are greasable.for long life. Lightweight Design QA1 street control arms were designed to be the strongest, best looking control arms on the market. And weighing in at less than 8lbs per arm, this makes them among the lightest of street worthy control arms available. Easy, Bolt-In Installation Our commitment to thoughtful product design is evident in every product we produce, to deliver the highest level of performance at the track, while ensuring trouble-free compatibility. Made in the USA QA1 control arms are proudly made in Lakeville, Minnesota. Fitment Notes Control arms allow +/- 1/8 adjustment from factory length Compatible with factory and QA1 K-members Coilover struts required, not compatible with factory coil springs Fox Body control arms include adapter for SN95 spindles
