Product Description

The QA1 LK12-FF04 Lowering Kit is a complete suspension package designed specifically for 2021-2025 Ford F-150 trucks in 4WD configuration. It enables a front drop of approximately 3" to 5" using the included drop spindles, while the rear is lowered approximately 3.5" to 5.5", with the possibility of an additional ~1.5" drop on 4WD trucks through removal of the factory rear blocks.

Built for truck owners who demand aggressive stance *and* performance, this kit pairs premium components like double-adjustable shocks, heavy-duty chromoly T-bars and polyurethane bushings - engineered for the weight and ride demands of modern trucks. Stand-out ride quality and handling control are made possible through the independent tuning of rebound and compression settings.

Installation is straightforward thanks to the fully bolt-in design - no cutting or welding required. Owners should note the requirement for 22" or larger wheels when using the spindles and the exclusion of PowerBoost hybrid models and F-150s equipped with the CCD (Continuously Controlled Damping) suspension. Fitment is confirmed through model year 2025.
