QA1 Mustang race lower control arms combine lightweight, durable construction with a clean look. A unique eccentric adjustment sleeve allows precise camber tuning and up to 1/2 inch of track width adjustment without removing the arm from the car. The forged ball joint housing adds reliability and strength, and the low friction ball joint is rebuildable and greaseable for easy maintenance. Ultra-low-friction greasable composite bushings are stiffer than rubber for bind-free movement and better response, and at less than 8 lbs per arm they are among the lightest street worthy control arms available. Installation is a bolt-in job.
