4" 2015-2020 Ford F150 4WD Lift Kit by Rough Country

This Rough Country 55530 /55531 4 inch lift kit for the Ford F-150 is a great upgrade for an aggressive new look and unparalleled off-road performance. Featuring a set of durable lifted knuckles and strut spacers or lifted struts, you'll gain enough ride height to run up to 33-inch tires with proper wheel spacing! A set of differential drop brackets, sway-bar drop brackets, brake line brackets, and a drive shaft spacer help keep everything at optimum angles for a factory-like ride, even after lifting. A 1/4-inch thick plate steel front and rear crossmember bring uncompromised strength and good looks to your truck, and are updated to fit the new F-150 design. Our Fabricated Rear Blocks offer considerably more strength than their cast iron counterparts, and were specifically engineered by Rough Country to prevent against axle-wrap.
