Built for Super Duty owners who want 6 inches of ground clearance and the ability to run 35"–37" tires while keeping factory geometry intact. Rough Country's 6-inch suspension lift kit delivers the height you need without sacrificing ride quality or handling. The radius arm drop brackets preserve proper caster angles, and the fabricated anti-wrap rear blocks eliminate binding — so your truck handles like it was engineered this way from the factory.
