Redefining Expectations

One-piece bed covers open and close like a trunk lid, providing some of the best sealed coverage for a truck bed available. Hydraulic struts allow the cover to easily lift and lower with one hand. UnderCover’s one-piece, hinging truck bed covers are light-weight, easy to install, and even easier to remove when you need full-bed access. All UnderCover flex bed covers come equipped with a secure locking system and a super-bright LED lighting system with a self-contained battery source.

The beauty of a one-piece tonneau cover from UnderCover is that there are several options of covers to choose from, many of which can be customized to match the color of your truck. Each one offers simple operation, reliable security, and aerodynamic style lines, while some models ramp up convenience and finish with features like locking handles, handy cargo retrievers, and carpet-lined under panels.

UnderCover’s tri-fold tonneau covers allow for full bed access and can be secured in multiple driving positions. UnderCover offers several of these options as well, include a true premium entry-level cover with easy ‘on and off’ functionality. Premium features can be found in this line, too, including dual action tailgate seals, carpeted under panels, an integrated luminous rail light system, and a durable LINE-X coating.

UnderCover is credited with introducing the first truly competitive alternative to the traditional fiberglass truck bed cover. The UnderCover Classic hit the market in 2001 and since then, UnderCover engineers have continued to churn out hits. In June of 2010 UnderCover, Inc. joined the Truck Hero, Inc. family of brands, a market leading company known for its quality and breadth of product lines, engineering, and innovation.
