About this kit
4-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 57431 is a 4-inch lift kit for the 2014 Ford F-150 4WD, covering XL through Limited trims plus FX4, STX, XLT, Lariat, King Ranch, and Platinum. The kit pairs a loaded strut pair with an N3 shock pair and clears tires up to 35 inches. It does not fit Raptor models or trucks with the Heavy Duty Payload Package (seven-lug).
This 4-inch lift kit for the 2014 Ford F-150 4WD ships as a set of boxed subassemblies: a universal kit box, a crossmember box, driver and passenger knuckles, a 4-inch block and U-bolt kit, a loaded strut pair, and an N3 shock pair. Front and rear crossmembers are 1/4-inch plate steel, and drop brackets keep the differential, sway bar, and brake lines at proper angles. Minor cutting and drilling is part of the job. Confirm your truck is not a Raptor or a seven-lug Heavy Duty Payload Package model, then work from the downloadable Rough Country installation guide.
