Description

QA1 sway bars afford improved handling and control by reducing body roll. They're manufactured from lightweight 4130 chromoly steel and 1045 cold-formed steel—with a gloss black powdercoat finish for maximum strength, endurance, and corrosion resistance. The QA1 sway bars are precision CNC-formed, ensuring proper mounting in the stock location for a true bolt-on installation. They also feature adjustable end links to customize roll stiffness to your personal specifications. These sway bars from QA1 include greaseable graphite polyurethane bushings, along with high-quality zinc plated hardware. Engineered and road-tested to give your ride the grip that it needs to hold the road, QA1 sway bars are available for fitment on many vehicle applications. Order them individually for the front or rear—or in a complete kit.
