These kits include the rack tray, wind deflector, track and feet - everything you need to mount a Slimline II Rack to truck canopies/camper shells/caps and trailers. The Slimline II Tray mounts to supplied Feet that slide into the supplied Track. The Track can be easily mounted to your canopy/shell or trailer with the supplied fasteners. If you currently have track in your canopy or trailer, we recommend replacing it with the stronger, integrated Front Runner track.
Please Note: Taller kits have space for mounting the Front Runner tables or other compatible accessories UNDERNEATH the rack.
