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 or double adjustable coil-overs. 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 2" drop spindles 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.
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. This kit features QA1’s single or double adjustable coil-overs, allowing you to set your preferred ride height and fine-tune ride quality with 18 clicks of adjustment. It’s easy to adjust on the vehicle and delivers a noticeable improvement in both comfort and control.
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.
