Get the stance, comfort, and control you want with a true bolt-on suspension system for your 1999-2006 NBS truck. Designed for 2WD short bed Silverado and Sierra 1500 models, this QA1 Level 1 kit includes front coil-overs and a matched rear drop system that transforms how your truck looks and drives. It’s the perfect upgrade for daily drivers, weekend cruisers, or anyone wanting to refresh and personalize their ride without cutting or welding.

RIDE HEIGHT ADJUSTABILITY WITH COIL-OVER CONTROL

QA1’s front coil-overs give you 0" to 2" 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 2" to 4" up front. Whether you're aiming for a subtle level or a slammed street look, this setup lets you get it just right.

REAR DROP KITS FOR THE PERFECT STANCE

Everyone’s idea of the perfect stance is a little different. That’s why this kit includes a matched rear drop system designed to lower the rear of your Silverado or Sierra by 2"–4". Clean design and strategic use of shackles, hangers, and QA1 shocks deliver the drop you want while keeping costs in check by reusing key factory components where possible.

DIAL IN YOUR COMFORT AND PERFORMANCE

Tailor the driving feel to your liking with QA1 single adjustable shocks. Daily drivers will appreciate the simplicity of single adjustable tuning. These shocks offer 18 clicks of combined compression and rebound adjustment to dial in a balance of performance and comfort.
