Product Overview Upgrade your NBS truck’s front suspension geometry and durability with QA1’s tubular upper control arm kit. Designed specifically for lowered or performance-built 2WD Silverado and Sierra 1500s, these arms help maintain proper alignment, improve ride quality, and add strength where it counts. BETTER GEOMETRY, STRONGER DESIGN Factory control arms weren’t made for today’s performance demands or lowered setups. QA1’s tubular design improves caster for better stability and helps maintain proper alignment throughout suspension travel. They're lighter than stock and compliment QA1 coilovers perfectly. STRAIGHTFORWARD, BOLT-ON INSTALL These control arms are a direct bolt-in replacement for OEM uppers and work with stock or QA1 drop spindles (Part Number: 9056-120). They come fully assembled with ball joints and bushings pre-installed. MADE IN THE USA QA1 NBS control arms are proudly made in Lakeville, Minnesota and built to last with a durable powder coat finish. Fitment Notes: Fits 1999–2006 Chevrolet Silverado / GMC Sierra 1500 2WD with coil front suspension: Not compatible with vehicles originally equipped with torsion bar front suspension
