QA1 Control Arm Kit, Lower, Race (79-93 Mustang) - 52540
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.
