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.

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.
