The Zone Offroad front box kit for 2017–2020 Ford Super Duty supports a 4-inch front lift and provides the front-specific components for those model years. Sold as a vehicle-tailored kit segment, it should be combined with the kit’s remaining parts and hardware to achieve the intended front ride height increase while maintaining proper suspension and steering fitment on compatible Super Duty trucks.
