Give your truck bed a clean, smooth edge while bettering your gas mileage. The Extang Tuff Tonneau III closes with sleek, flat edges by using the new J45 “peel & seal” system.

Hauling large loads with the Tuff Tonneau III is easy with the quick release tail rail and spring-loaded Monster Bows. Inspired by the bed covers used to make racing trucks sleeker, the Extang Tuff Tonneau III boasts a heavy-duty black leather grain vinyl tarp that's covered by a 10-year warranty. Your Extang Tuff Tonneau III Cover features a durable frame backed by a Lifetime Warranty.
