6 Inch Lift Kit | Gas | 4 Link | Rr Spring | C/o V2 | Ford F-250/f-350 Super Duty (05-07)

Built for Ford Super Duty owners who demand serious lift with factory-correct geometry — this 6-inch 4-Link Coilover Conversion Lift Kit replaces your factory independent coil setup with a full adjustable suspension system and Rough Country Vertex 2.5" monotube coilovers. You'll gain 6 inches of ground clearance, ride-height adjustability, and the ability to set proper caster for handling that rivals stock — all while fitting 35"–37" tires.
