Give your F-150 an aggressive new look and unparalleled off-road performance with Rough Country's 4" Suspension Lift. This all-inclusive kit features everything needed to take your off the freeway and into the fields. Featuring a set of durable lifted knuckles and N3 Loaded Coil Spring Struts, you'll gain enough ride height to run up to 35" tires! A set of differential drop brackets, sway-bar drop brackets, brake line brackets, and a drive shaft spacer help keep everything at an optimum angle for a factory-like ride, even after lifting. A 1/4" thick plate steel front and rear cross member bring uncompromised strength and good looks to your truck, featuring a laser-cut X logo and an easy-to-install 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 performance off-road N3 shock absorbers are included. Backed by Rough Country's Lifetime Warranty.
