The Kargo Master Pro II Series Truck Ladder Rack is one of the toughest heavy-duty racks in the market. The Kargo Master Pro II Series Truck Rack is built with 2" diameter round steel tubing that has a 1,700 lb. loading capacity. The sleek round tube design significantly reduces wind drag and noise and creates an uniform load distribution that results in a sturdier rack. All Kargo Master truck racks are treated with zinc primer and marine grade powder coat to achieve excellent corrosion and UV resistance. Pro II Steel Truck Racks are available for all full size trucks in a standard and extended/crew cab style that fits 6.5ft and 8ft bed lengths. Extended length racks position the front crossbar beyond the windshield on extended cab trucks. This reduces wind noise, looks better, and provides more support for long cargo.
