Description

IMPORTANT NOTICE: Not compatible with vehicles originally equipped with torsion bar front suspension and factory sway bar. Must use QA1 sway bar 52869.

Product Overview Upgrade the front suspension of your NBS truck with QA1’s complete coil-over and control arm kit. Designed for 2WD 1999–2006 Silverado and Sierra 1500s, this system includes tubular upper and lower control arms and QA1’s single adjustable coil-overs DIAL IN THE PERFECT STANCE QA1’s front coil-overs give you 1" to 3" of ride height adjustability right out of the box. Want to go lower? Pair them with QA1’s 2" drop spindles (Part Number: 9056-120) for a total drop range of 3" to 5" up front. Whether you're aiming for a subtle level or a slammed street look, this setup lets you get it just right. IMPROVED GEOMETRY WITH BOLT-ON CONTROL ARMS The included QA1 upper and lower tubular control arms are built to improve suspension geometry and increase strength over stock. They offer more clearance for coil-overs, reduce deflection under load, and help maintain proper alignment. RIDE QUALITY YOU CAN TUNE This kit features QA1’s single adjustable coil-overs, allowing you to set your preferred ride height and fine-tune damping with 18 clicks of combined compression and rebound adjustment. It’s easy to adjust on the vehicle and delivers a noticeable improvement in both comfort and control. STRAIGHTFORWARD, BOLT-ON INSTALL This system bolts directly into place using standard tools—no welding required. QA1 includes everything you need for a smooth install, with pre-installed ball joints and bushings in both control arms to save you time. MADE IN THE USA QA1 NBS suspension is proudly made in Lakeville, Minnesota and built to last with a durable powder coat finish.
