Chevrolet Silverado 1500 Sway Bar - Rear - QA1 - 1-1/4in - `99-`06 is a direct-fit rear anti-roll bar designed for 2WD Silverado and Sierra 1500 models. This QA1 1.25" rear sway bar tightens rear-end response and reduces body roll for improved handling without major modification.

Built to complement QA1 torque arm rear suspension and front sway bar setups, the QA1 52880 bar increases rear stiffness for a more balanced feel through corners, especially on lowered trucks or those with QA1 coil-over conversions. The kit is a bolt-on design that includes bushings, brackets, and hardware so installation can be completed with basic hand tools—no cutting or welding required. Finished in a durable powder coat and made in Lakeville, Minnesota, this rear sway bar is precision-formed for consistent fit and long-term use.
