QA1 Mustang street lower control arms combine lightweight, durable construction with a clean look. The forged ball joint housing adds reliability and strength, and the low friction ball joint is rebuildable and greaseable for easy maintenance. Greasable polyurethane bushings are stiffer than factory rubber for better stability and a more responsive ride, and at less than 9 lbs per arm they are among the lightest control arms available. Installation is a bolt-in job, and the arms are made in the USA in Lakeville, Minnesota.
