Give your '11 - '13 Ford F-150 an aggressive new look and unparalleled off-road performance with Rough Country's 6-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 or N3 lifted struts, you'll gain enough ride height to run up to 35-inch 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-inch thick plate steel front and rear cross member bring uncompromised strength and good looks to your truck, featuring a laser-cut "RC" logo and an easy-to-install design. Our 4-inch Fabricated Rear Blocks offer considerably more strength than their cast iron counterparts, and were specifically engineered by Rough Country to prevent against axle-wrap. Improve your on and off-road ride quality with Rough Country's premium N3 shocks! These 10-stage variable valving, high-pressure Nitrogen charged shocks offer a fantastic blend of off-road action and smooth highway ride quality. With a durable 18mm spring-loaded piston rod and faster-cooling 54mm shock body, this shock offers up to 36kN Tensile Strength for a long lifespan of impressive vibration dampening.
