The QA1 lowering kit is an all-in-one solution for anyone looking to upgrade the suspension of their 2021-2026 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.

Features

• 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 for a leveled look or a 5/5 drop for an aggressive raked look, QA1's lowering kit with drop spindles is the ideal solution to achieve the perfect stance. For the rear, you can lower it within a range of 3.5-5.5" with ½-inch increment adjustments on 2WD trucks. 4X4 trucks will see an additional 1.5" of lowering in the rear.
• 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.
• Double-Adjustable Shocks: Take your F-150's performance to the next level with QA1 double adjustable 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 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.
• Traction Bars: Lowered F-150s with added power often fight wheel hop and traction issues. QA1's traction bar system is engineered to control axle movement while maintaining ride quality and everyday drivability. Designed for street-driven performance trucks, it delivers the grip and stability owners want without harshness, excessive noise, or reduced ground clearance.
• 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.
