Fits select 2021-2026 Ford F-150 models including XL, XLT, Lariat, King Ranch, Platinum, and Raptor. This QA1 lowering kit (LK01-FF03) provides a comprehensive suspension solution, combining front Pro Coil coil-overs with a rear drop kit to achieve a custom stance while significantly enhancing ride quality and handling performance.

Single-adjustable valving allows you to simultaneously tune compression and rebound with a simple knob adjustment to suit your driving preference.
