About this part

Transform Your F-150 with Aggressive Style and Trail-Ready Performance: Take your Ford F-150 to the next level, both in looks and capability, with Rough Country's 6-Inch Suspension Lift Kit. Engineered for serious off-road enthusiasts, this all-inclusive kit gives your truck a commanding stance and the clearance needed to conquer rugged terrain with confidence. Built for the Trail. Designed for the Road: Gain increased ground clearance and install up to 35-inch tires with proper spacing, without compromising ride quality. The heavy-duty lifted knuckles and precision-engineered strut spacers deliver reliable height and strength, while differential drop brackets, sway-bar drop brackets, brake line brackets, and a driveshaft spacer keep vital components at factory-like angles for a smooth, controlled ride. Unmatched Durability with Fabricated Components: Front and rear 1/4-inch plate steel crossmembers add aggressive style and rock-solid support, customized to fit the latest F-150 chassis. Rough Country's fabricated rear blocks are stronger than cast options and built to last, featuring specially designed anti-axle wrap geometry that maintains stock ride quality while eliminating common lift block issues. Clears Bigger Tires with Confidence: This lift provides the clearance to run 35-inch tires, giving your F-150 a bold new look and serious off-road potential. Fully Configurable with All Shock and Strut Options: Customize your ride with the suspension setup that fits your driving style. Choose from nitrogen-charged N3 shocks for balanced on- and off-road performance or upgrade to Rough Country's Vertex reservoir series for premium ride quality and maximum damping control. Peace of Mind Included: Rough Country backs this kit with a Limited Lifetime Replacement Guarantee, ensuring your suspension is ready for whatever comes next.
