QA1 Pro Coil Coilover Kits give you complete control over the ride height of your 2019-2026 Silverado 1500 or Sierra 1500. This fully bolt-in system replaces the factory front struts and allows both 2WD and 4WD trucks to achieve the stance you're after. Adjust ride height from a 2"-4" drop when used with drop spindles or 0"-2" with factory spindles.
DIAL IN YOUR RIDE HEIGHT:
Finding the right stance is easy with QA1 Pro Coil Coil-Over Kits. Fully threaded aluminum shock bodies allow precise ride height adjustment, making it simple to fine-tune your truck's appearance and suspension setup.
DOUBLE-ADJUSTABLE COIL-OVERS:
Double-adjustable Pro Coil shocks provide independent rebound and compression adjustment, allowing you to tune ride quality and handling for your specific application. Whether you're looking for improved street performance or dialing in a truck that sees occasional track use, these shocks offer the flexibility to match your driving style.
HEAVY-DUTY SHOCK DESIGN:
Engineered specifically for today's full-size trucks, these heavy-duty Pro Coil shocks are built to support vehicle weight and payload demands. Polyurethane bushings and a 1" chromoly T-bar provide long-term durability while eliminating the maintenance associated with spherical bearings, making them well suited for daily-driven trucks.
