This QA1 lowering kit is an all-in-one solution for anyone looking to upgrade the suspension of their four-wheel drive 2007-2016 Silverado 1500 / Sierra 1500 with cast steel control arms. This kit includes QA1's front Pro Coil Coil-Overs, 2” Drop Spindles and 4/6 Rear Drop Kit, 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. If you're looking for a 4/6 drop or looking to be even a bit lower, QA1's lowering kit is the ideal solution to achieve the perfect stance for you. The front coil-overs and drop offer a drop range of 3"-5" in the front. For the rear, you can lower it within a range of 4-6" with ½-inch increment adjustments.
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
Double-Adjustable Shocks
Upgrade your Silverado's performance to the next level with QA1 double adjustable Pro Coil shocks. Perfect for both street and track use, double adjustable shocks are famous for their independent rebound and compression tunability, giving you exceptional handling and control for finer control over your suspension.
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.
