Give your 2015-2016 Ford F-150 an aggressive new look and unparalleled off-road performance with Rough Country's 4-inch Suspension Lift. This all-inclusive kit features everything needed to take your Ford off the freeway and into the fields.Featuring a set of durable lifted knuckles and strut spacers, 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. A set of Rough Country's premiere off-road shock absorbers - Performance 2.2's - are also included in this kit, featuring a large 2.2-inch diameter body with a chrome-hardened piston rod and long-lasting polyurethane bushings.Best of all, Rough Country's 2015 Ford F-150 Lift Kit is backed by our Lifetime Replacement Warranty.
