About this kit
4-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 55530 is a 4-inch lift kit for supported 2015–2020 Ford F-150 4WD models, built around fabricated rear blocks, front struts, replacement knuckles, a crossmember, and an N3 shock pair. It does not fit regular or standard cab trucks, and installation calls for cutting and drilling.
This 4-inch lift kit for the 2015–2020 Ford F-150 4WD arrives as a boxed kit: a block and U-bolt package for the rear, a strut box for the front, a crossmember, replacement knuckles, hardware, and an N3 shock pair. It keeps the factory track width and works with 18-inch or larger factory wheels, and the rear block design targets axle wrap. Regular and standard cab trucks are excluded. Trucks staying on factory wheels should stay at or under an 11.5-inch tire width. Cutting and drilling are part of the job — review the downloadable Rough Country installation guide first.
