Description
This QA1 lowering kit is designed to drop your 2019–2026 Silverado 1500 or Sierra 1500 while improving ride quality, control, and stance. Built around QA1 single adjustable Pro-Coil front coilovers and matched rear shocks, it allows you to fine-tune ride feel with a simple turn of a knob. If you want a proven 4/5 drop that balances comfort, control, and ease of installation, this kit delivers. MODERN HANDLING AND ADJUSTABILITY Lowering a modern truck should enhance how it drives, not make it harsher or less predictable. This kit uses QA1 single adjustable shocks up front and in the rear to give you real control over ride firmness. With one adjustment, you can dial the suspension to match daily driving, highway cruising, or a more planted street feel. The result is a lowered Silverado that still drives like a truck you want to spend time behind the wheel of. ENGINEERED FOR STRENGTH AND STREET USE 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 uses matched springs, shock valving, thrust bearings, and mounting hardware to deliver smooth adjustment and consistent performance. By pairing properly matched front and rear components, this kit avoids the compromises of pieced-together lowering solutions and keeps your suspension working as a complete system. BOLT-IN CONVENIENCE This lowering kit is designed as a bolt-in solution for 2019–2026 Silverado 1500 and Sierra 1500 trucks in both 2WD and 4WD configurations. No cutting or welding is required, making it a straightforward upgrade for builders who want results without unnecessary complexity. Included drop spindles help achieve the desired drop while maintaining suspension geometry, and the rear mounting hardware and shock package are designed to support a clean 3–5 inch drop.
