3/5 Lowering Kit, 15-20 F150 4WD, W/Spindles, Double Adjustable (PART #QA1-LK12-FF02)

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 used with QA1 drop spindles. For the rear, you can lower it within a range of 3.5-5.5" with 1⁄2-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.

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.

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.
