About this kit
6-Inch Lift Kit, Loaded Struts & N3 Shocks — F-150 4WD (2021-2026), fitment-checked
Rough Country 49931 is a 6-inch lift kit for compatible 2021-2026 Ford F-150 4WD trucks, built around a loaded strut pair up front, an N3 shock pair out back, and forged aluminum steering knuckles. Wheels must measure 20 inches or more in diameter to clear the supplied knuckle. Single-cab trucks, two-piece driveshafts, CCD-equipped models, the 3.0L Power Stroke Turbo Diesel V6, and Tremor trucks with their 1-inch factory lift are all outside the fitment.
This 6-inch lift kit for the 2021-2026 Ford F-150 4WD covers listed trims from XL and STX through Lariat, King Ranch, Platinum, and Limited, plus Police Responder and SSV applications. The boxed kit ships as six line items: the 6-inch rear kit box, a crossmember box, aluminum knuckles, a loaded strut pair, an N3 shock pair, and the main kit box. Fabricated rear blocks are designed to limit axle wrap while holding factory track width. Plan on cutting and drilling during the job, and check the exclusion list and the 20-inch wheel minimum before you order. A downloadable installation guide is available.
