Product Overview Upgrade your NBS truck’s suspension with QA1’s tubular lower control arms—purpose-built for use with QA1 coil-over systems. These arms are a must-have for lowered or performance-driven 2WD Silverado and Sierra 1500s, offering improved geometry, added strength, and better clearance for coil-over setups. DESIGNED FOR COIL-OVER PERFORMANCE Unlike factory arms, QA1’s tubular lower control arms are engineered specifically for coil-over applications. They improve suspension geometry, reduce weight, and provide the clearance needed for QA1’s front coil-over shocks—giving your truck the stance, handling, and reliability you expect from a serious suspension upgrade. STRAIGHTFORWARD, BOLT-ON INSTALL These lower control arms are a direct bolt-in replacement and are designed to work with QA1 front coil-overs and drop spindles (Part Number: 9056-120). Each set comes fully assembled with ball joints and bushings installed, making installation easy and efficient. MADE IN THE USA QA1 NBS control arms are proudly made in Lakeville, Minnesota and built to last with a durable powder coat finish.
