Rear Sway Bar, 99-06 Silverado/Sierra 1500 2WD
QA1 #52880
Tighten up the rear end of your NBS truck with QA1’s 1.25" rear sway bar kit. Designed for 2WD Silverado and Sierra 1500 models, this upgrade helps improve rear-end stability, reduce body roll, and bring better balance to your truck’s handling—especially when paired with QA1’s front sway bar and torque arm rear suspension.
LESS BODY ROLL, MORE CONTROL 
A larger 1.25" diameter delivers increased stiffness and helps keep your truck composed through corners. It’s the perfect addition for trucks with lowered suspension or those running QA1’s torque arm system.
STRAIGHTFORWARD, BOLT-ON INSTALL
This sway bar is designed to bolt on with no cutting or welding required. It comes complete with bushings, brackets, and hardware to make installation smooth and simple using basic hand tools.
