Product Overview
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 single or double adjustable Pro Coil front suspension, a matched single or double adjustable rear drop kit, and optional integrated traction bars, it gives you full authority over ride quality and power delivery.
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.
Optional QA1 traction bars add another layer of control by reducing wheel hop and helping keep power planted during acceleration. The result is a Silverado that not only looks aggressive, but stays composed when driven hard.
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.
