Product Overview Looking to step up your NBS truck’s stance, comfort, and handling? QA1’s Level 2 Handling Kit is a complete, bolt-on solution designed for 2WD short bed Silverado and Sierra 1500 models. This kit includes double adjustable coil-overs, drop spindles, upgraded control arms, beefy sway bars front and rear, and a torque arm rear suspension system—giving your truck a more planted and stable feel. ADJUSTABLE COIL-OVERS FOR A BETTER RIDE AND STANCE This kit includes QA1’s double adjustable rear coil-overs, giving you 18 clicks of compression and rebound adjustment to fine-tune how your truck rides and handles. With up to 4"–7" of drop range, you can set the perfect stance while still enjoying a comfortable, confident ride. MULTI-LINK TORQUE ARM FOR MAXIMUM TRACTION Instead of traditional leaf springs, this kit uses a multi-link torque arm design to improve traction and ride quality. It eliminates suspension bind, helps transfer weight more effectively, and gives you more control over pinion angle. BETTER GEOMETRY AND LESS BODY ROLL Upgraded QA1 tubular front control arms improve suspension geometry, while 2” drop spindles provide a great-looking stance. A 1.5" front sway bar and 1.25" rear sway bar help reduce body roll, giving your truck a planted, stable feel. STRAIGHTFORWARD, BOLT-ON INSTALL This kit is fully bolt-on and installs easily with basic hand tools, no welding or specialty equipment needed. You will need to remove the factory crossmember, but don’t worry—QA1 includes a replacement designed to bolt right in while retaining your factory fuel system.
