Product Overview QA1 Pro Coils are a great option if you're looking to customize the ride height of your 07-18 Silverado 1500 / Sierra 1500. It's a fully bolt-in solution that replaces the OE system, allowing both 2WD and 4WD owners to customize their ride height to their liking. With a drop of 3"-5" using drop spindles or 1"-3" with stock spindles, this kit provides the perfect stance for your truck. Ride Height Adjustability We understand that achieving the perfect stance for your truck can be a challenge. That's why we've created a solution that makes it easy to adjust your ride height. Pro Coil kits feature fully threaded, aluminum body Pro Coil shocks which allow you to effortlessly dial in how your truck sits. Double-Adjustable Coil-Overs For performance enthusiasts who demand the ultimate in handling and control, our double-adjustable Pro Coil shocks are the perfect choice. These shocks offer independent tunability for both rebound and compression, allowing you to fine-tune your suspension for optimal performance on the street or track. Heavy Duty Shock Design QA1 Engineers have tackled the challenge of supporting the weight and payload capacity of modern trucks by designing a heavy-duty version of our Pro Coil system, which features an upgraded shock with polyurethane bushings and a 1" chromoly T-bar. The system's new bushing design was specifically chosen to withstand the daily use of trucks, rather than using spherical bearings.
