Product Description:
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 double 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 includes QA1’s double adjustable coil-overs, giving you 18 clicks of independent compression and rebound adjustment to fine-tune how your truck rides and handles. 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.
