6 Inch Lift Kit | Diesel | C/o Vertex | Ford F-250/f-350 Super Duty (05-07)

Built for first-generation Super Duty owners who want commanding ground clearance without sacrificing ride quality, this 6-inch coilover conversion lift kit transforms your truck's suspension geometry while keeping factory handling intact. Run up to 37-inch tires and preserve smooth, predictable driveability with Rough Country's Vertex coilover system — a complete front and rear overhaul that replaces the factory independent coil setup with 2.5-inch adjustable shocks.
