Product Overview 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, drop spindles, and Rear Drop Kit, which provide maximum adjustability to achieve the perfect lowered stance, while providing significant improvements to ride quality and performance. Ride Height AdjustabilityQA1 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. Front coil-overs provide a drop range of 3"-5" with the included drop spindles. Lower the rear with a drop range of 4-6". 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. Single-Adjustable Shocks QA1 Proma Star single 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.Rear Shackles and Hanger KitsQA1'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 InstallationOur commitment to thoughtful product design is evident in every fully bolt-in kit we produce, which guarantees a hassle-free installation process.
