Titan truck bed toolboxes bolt to the top of their 60 gallon in-bed fuel tank models. Constructed of heavy-gauge aluminum diamond plate, they feature plated locks for security and an air spring-supported lid for convenience. They are available in compact and large sizes with either a bright or black finish. All are designed with two compartments–one for tools and one which completely houses the fill neck and fuel gauge, plus transfer pump kit (large models only) when installed. Titan truck bed toolboxes protect fuel, tank components, and tools from theft and the weather. The boxes will hold up to 100 lbs. of tools.
