Add an extra 800 pounds of cargo-hauling capacity without drilling holes in your truck bed. The Guide Gear® Full-Size Universal Truck Rack installs in 30 minutes or less using basic hand tools. Patented combined clamps and gold zinc-plated hardware add maximum strength and durability. In addition, the lightweight aluminum construction won't rust and shoulders up to 800-lbs. of cargo. The cross bars are fully adjustable to fit the demands of your load and a removable rear bar lets you add taller items to the bed without needing to remove the entire rack.
