All Front Runner Rack Kits contain installation instructions as well as all the components needed to mount the Slimline II Tray to your vehicle. NOTE: Your vehicle must be equipped with the factory/OEM roof rails in order to use this rack kit. This rack kit can be removed leaving your vehicle’s roof and roof rails in their original condition. All Front Runner Racks are backed by a Limited Lifetime Warranty* Factory Rail Rack Kits are designed as a ''light duty'' cargo solution. Please refer to your vehicles owner manual for manufacturers recommended load rating and do not exceed these limits. For optimal load carrying capacity, we recommend that there is no cargo overhang (excludes sports gear) and all weight is distributed evenly across the rack. Factory Rail Rack Kits are not suited for extreme off-road conditions and therefore you should consider a different Front Runner mounting solution if this is your intended purpose. Please contact us for advice on specific mounting solutions for your vehicle and use.
