Lowered Look, Unmatched Ride Comfort.
The QA1 lowering kit is an all-in-one solution for anyone looking to upgrade the suspension of their 2015-2020 Ford F150. This kit includes both QA1's front Pro Coil Coil-Overs and Rear Drop Kit, which provide 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.
Whether you're looking for a 3/5 drop or aiming to go even lower, QA1's lowering kit is the ideal solution to achieve the perfect stance. The front coil-overs offer a drop range of 3"-5" when using kits with included drop spindles, or 1"-3" with stock spindles. For the rear, you can lower it within a range of 3.5-5.5" 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 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.
QA1 Proma Star single and double adjustable shocks deliver exceptional ride quality and performance to your F150. 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 Flip Kit, Shackles and Hanger Kits
QA1's Rear Flip Brackets, 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.
