There are many products in the aftermarket that will help to keep the bed of your GMC looking great for many years. One, however, will also help to decrease the amount of fuel you use, and it is a GMC tonneau cover. The air rushing over the cab of the truck may hit the tailgate, which will inevitably cause a certain amount of drag. With a GMC tonneau cover installed, the air glides smoothly over the entire truck, reducing drag, and thus increasing gas mileage. With gasoline as expensive as it is today, every little bit helps. The GMC tonneau cover also takes the utilitarian lines of the bed, and hides them, for more streamlined and sleek appearance. With a sealed GMC tonneau cover, you also gain a large amount of dry storage, while it protects the finish of your bed from water, salt, and other undesirable elements. It usually comes in black, and it requires no permanent modifications to your truck to install it. Therefore, it will not void your warranty or detract from the resale value of the vehicle. The soft version of the GMC tonneau cover is made of a heavy-duty material, which is easily rolled up when it is necessary to carry larger items. The hard version is made of lightweight fiberglass and it includes pistons to assist in lifting it open. For those who need a secure storage area, the hard GMC tonneau cover is available with a superior locking system, and the unit can also be painted to match the color of your truck. Along with the GMC tonneau cover, easily ordered online or via our 24-hour toll-free telephone number, we carry a full line of other parts and accessories for your GMC.
