The racks are made for trucks that work hard during the week and still need to look sharp when the job is done.\u003c\/p\u003e\n\u003cp\u003eEvery BackRack frame mounts to the bed through a truck-specific installation kit. Separate kits let the rack live alongside a crossover toolbox, a bedliner or a tonneau cover that clamps to the inside of the bed rail.\u003c\/p\u003e\n\u003cp\u003eBecause a BackRack sits low behind the cab, the truck still fits in a home garage and multi-level parking. Light brackets, tool holders, side rails and a rear bar turn the same frame into a platform for lights, long loads and gear, and the steel is finished in a powder coat applied in house.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BackRack","offers":[{"title":"Default Title","offer_id":67740812214516,"sku":"40109","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/4784\/0244\/files\/backrack-tonneau-adapter-installation-kit-black-tonneau-adapter-bracket-with-realtruck-1.jpg?v=1791453641","url":"https:\/\/prestigetruck.com\/products\/backrack-tonneau-cover-adapter-kit-1999-2007-chevrolet-gmc-40109","provider":"Prestige Truck","version":"1.0","type":"link"}
