Convert your Front Runner Slimline II Roof Rack at any time to a classic looking safari style basket shaped roof rack. No drilling is required for installation, and the kit adds extra cargo support with an attractive, low-profile design. Mounting hardware is included, and the rails are powder-coated with the same durable, weather-resistant finish as the Slimline II Roof Rack. The Expedition Rails add 63mm / 2.5'' to the height of the roof rack and are manufactured with corrosion-resistant, high-density aluminum components. * Note: A maximum driving speed of 130km/80mi per hour should be adhered to, when equipped with a Front Runner Roof Rack or Load Bar kit.
