This 1762mm/69.4'' long, full-size, Slimline II Cargo Roof Rack Kit contains the Slimline II Tray, Wind Deflector and 6 Grab-On Feet to mount the Slimline II Tray to the roof rails of your Ford Expedition or Lincoln Navigator (2018-Current). This system installs easily with feet that grab on to the existing factory/OEM roof rails. No drilling required. \nAll Front Runner Rack Kits contain installation instructions as well as all components needed to mount the Slimline II Tray to your vehicle. \nRack kit can be removed temporarily so you can continue to use your OEM rails. \nAll Front Runner Racks are backed by a Limited Lifetime Warranty. \nFactory Rail Rack Kits are designed as a ''light duty'' cargo solution. Please refer to your vehicle owner’s manual for manufacturer’s recommended load rating. \nFor optimal load-carrying capacity, we recommend that weight is evenly distributed across the rack, and that there is no cargo overhang (excluding sports gear). \nFactory Rail Rack Kits are not suited for extreme off-road conditions. Please consider a different Front Runner rack solution for that purpose. \nPlease contact us for advice on mounting solutions for your specific vehicle and usage. \nNOTE: Your vehicle must be equipped with the factory/OEM roof rails in order to use this rack kit. \nNote: The load for Factory Rail Rack Kits must not exceed 88lbs or 40kg, and ensure the load is distributed evenly.
