About this kit
4.5-Inch Lift Kit, fitment-checked
Rough Country 51930 is a 4.5-inch lift kit for the 2017-2018 Ford F-150 Raptor 4WD. It reuses the factory struts and shocks and levels the front with the rear. Factory wheels cannot be reused: aftermarket wheels must be 18 inches or larger and stay within 9 inches of width, 0mm offset, and 5 inches of backspacing. Single-cab models are not covered.
This 4.5-inch lift kit for the 2017-2018 Ford F-150 Raptor 4WD keeps the factory struts and shocks in service, so ride character stays close to stock while front ride height comes up to match the rear. The front side of the kit includes lifted knuckles, a strut spacer assembly, front and rear crossmembers, sway-bar and differential drop brackets, brake line brackets, and a driveshaft spacer. Out back are fabricated anti-wrap blocks with built-in bump stops, a rear factory shock spacer, U-bolts, and brake line relocation brackets. Cutting and drilling are part of the job; Rough Country lists 5-6 hours, and a downloadable installation guide is available.
