Description

Product Overview If you're ready to move beyond stock leaf springs, QA1’s rear suspension system is the upgrade your truck’s been waiting for. Built specifically for 1999–2006 2WD Silverado and Sierra 1500s, it’s a major step up in traction, ride quality, and overall drivability. MORE TRACTION. NO BIND. BETTER STREET MANNERS The torque arm setup replaces your leaf springs with a true multi-link system that eliminates bind, improves pinion angle control, and helps your truck put power down more effectively. This is the kind of upgrade that makes your truck feel planted and predictable. DIAL IN YOUR RIDE WITH QA1 COIL-OVERS Tailor the driving feel to your liking with QA1 single adjustable shocks. These shocks offer 18 clicks of combined compression and rebound adjustment to dial in a balance of performance and comfort. With up to 4"–7" of drop range, you can set the perfect stance while still enjoying a comfortable, confident ride. BOLT-ON DESIGN WITH CROSSMEMBER REPLACEMENT You won’t need a welder or fabrication shop to get this done. QA1 includes a bolt-in fuel tank crossmember that replaces the rust-prone factory piece while keeping your stock fuel tank and lines in place. The full system installs with basic hand tools and includes all the necessary hardware and instructions. MADE IN THE USA QA1 Torque Arm suspension is proudly made in Lakeville, Minnesota. Fitment Notes Fits 1999–2006 Chevrolet Silverado 1500 2WD – Short Bed Only: For use with 10 bolt axle only: Rear sway bar not included—available separately (Part Number: 52880): Modification to exhaust required
