Transform your 1997-2003 Ford F-150 with Rough Country's 4-Inch Suspension Lift Kit, delivering a bold new look and the capability to dominate off-road terrain. This all-inclusive system is built for performance, durability, and aggressive stance, perfect for any adventure ahead. Achieve Aggressive Ride Height and Control: This kit includes heavy-duty lifted knuckles that provide the clearance needed to run up to 35-inch tires with proper wheel spacing. Differential drop brackets, sway-bar links, bump stop brackets, and torsion bar drop brackets help maintain factory-like ride quality by keeping components at optimal geometry. Built for Strength and Durability: A pair of high-strength front and rear steel crossmembers form the foundation of this lift, while Rough Country's fabricated rear blocks outclass traditional cast options for improved strength and long-term reliability on and off the trail. Engineered for Smooth Performance: Rough Country's premium N3 shocks are included, offering 10-stage variable valving, a high-pressure nitrogen charge, 18mm spring-loaded piston rods, and 54mm shock bodies. These features combine to deliver a smooth highway ride with firm off-road response. Peace of Mind Included: Rough Country backs this kit with a Limited Lifetime Replacement Guarantee, ensuring your suspension is ready for whatever comes next.
