Lowered Look, Unmatched Ride Comfort.

The QA1 lowering kit is an all-in-one solution for anyone looking to upgrade the suspension of their 07-18 Silverado 1500 / Sierra 1500's. This kit includes both QA1's front Pro Coil Coil-Overs, Rear Drop Kit, and optional drop spindles which provide maximum adjustability to achieve the perfect lowered stance, while providing significant improvements to ride quality and performance. 

Ride Height Adjustability

QA1 lowering kits offer easy and precise adjustments for your truck's stance. Fully threaded front coil-over shock bodies provide adjustment without the use of clumsy shims or spacers, while our rear drop kits offer 2” of adjustment to dial in the final rake of the truck. 

To achieve that perfect 2/3, 3/5 or 4/6 drop, the adjustable coil-overs and rear drop kits provide plenty of adjustment. Front coilover kits offer a 1-3" drop range, but when combined with optional drop spindles, you can achieve 3"-5" of drop. For the rear, choose from either a 2-3” or 4-6" rear drop. When buying a kit With Drop Spindles please see Fitment Notes Below.

Heavy Duty Shock Design 

QA1 Engineers have tackled the challenge of supporting the weight and payload capacity of modern trucks by designing the 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. 

Adjustable shocks

QA1 Proma Star single and double adjustable shocks deliver exceptional ride quality and performance to your Silverado. With the simple turn of a dial, you can effortlessly switch between a comfortable cruise and a more aggressive feel, making them ideal for daily driving or twisty backroads.

Rear Shackles and Hanger Kits

QA1's Rear Shackle and Hanger Kits are the ultimate solution for lowering the rear of your truck without compromising ride quality. Made from heavy-gauge steel with a powder-coated finish and top-notch hardware, our kits guarantee long-lasting performance in any driving conditions.

EASY, BOLT-IN INSTALLATION

Our commitment to thoughtful product design is evident in every fully bolt-in kit we produce, which guarantees a hassle-free installation process.
