    This QA1 lowering kit is designed to deliver a clean 4/5 inch drop on your 2019–2026 Silverado 1500 or Sierra 1500 while maximizing control, traction, and adjustability. Built around QA1 double adjustable Pro-Coil front suspension and a matched double adjustable rear drop kit, it gives you full authority over ride quality and power delivery. MODERN HANDLING AND ADJUSTABILITY Lowering a modern truck is about more than looks. This kit uses QA1 double adjustable shocks up front and in the rear, allowing independent tuning of compression and rebound to match your exact driving style. Whether you want a refined street ride or a firmer, more planted setup, the adjustment range gives you the flexibility to dial in performance without compromise. ENGINEERED FOR STRENGTH, CONTROL, AND TRACTION QA1 engineered this system specifically for the weight, suspension geometry, and real-world demands of late-model half-ton trucks. The Pro-Coil front suspension and double adjustable rear drop kit are designed as a matched system to maintain balance and predictable handling at a lowered ride height. BOLT-IN CONVENIENCE This lowering kit is designed as a bolt-in upgrade for 2019–2026 Silverado 1500 and Sierra 1500 trucks in both 2WD and 4WD configurations. No cutting or welding is required, making it an ideal solution for builders who want top-tier performance without custom fabrication. Included drop spindles help achieve the desired drop while maintaining suspension geometry, and the bolt-in traction bar system integrates cleanly with the rear suspension for added control.
