QA1 GS518-12800 Front Pro Coil Shock System
Overview
If you're looking to customize the ride height of your 2007-2018 Silverado 1500 or Sierra 1500, the QA1 GS518-12800 Front Pro Coil Shock System is an excellent choice. This fully bolt-in solution replaces the original equipment (OE) system, making it suitable for both 2WD and 4WD models. With the ability to lower your truck by 3"-5" using drop spindles or 1"-3" with stock spindles, you can achieve that perfect stance you’ve been dreaming of.
Key Features
Ride Height Adjustability
Finding the ideal stance for your truck can be tricky. The Pro Coil kits come equipped with fully threaded aluminum body shocks, allowing you to easily adjust your ride height to your liking.

Single-Adjustable Coil-Overs
The single-adjustable Pro Coil shocks are designed specifically for street-driven trucks that may also hit the track. With just a simple turn of the adjustment knob, you can switch between a comfortable ride and a firmer, more responsive setup whenever the situation calls for it.
