Built for Super Duty diesel owners who want an aggressive lifted profile without sacrificing factory handling, this 8-inch 4-link suspension lift kit delivers serious ground clearance while preserving the geometry that keeps your truck driving like a truck. Rough Country engineered this system to level the front with the rear, accommodate 37"–40" tires, and maintain balanced on and off-road ride quality through precision radius arm drop brackets and caster-correction control arms.
