The GMC Sierra was unveiled in 1999 as a full-size pickup truck, very similar to its sibling, the Silverado, which was introduced the same year. The Sierra is available in light-duty and heavy-duty configurations. The light-duty Sierra is developed for convenient everyday use, while the heavy-duty (HD) version of the truck features higher carrying capacity. The HD Sierra also offers higher towing capacity, as it is equipped with more powerful engine, compared to the lightweight version of the truck. Besides, for the first generation only heavy-duty Sierras were available with a Duramax diesel engine, while light-duty trucks came equipped with gasoline engines alone.

If you own a pickup truck, you definitely use it to transport some cargo in its bed, and you certainly know that it is always better to securely "hide" your belongings from prying eyes and moisture, extra sun or dust. If that is the case and you would like to cover the bed of your Sierra with a truck cap, we have what you need! In our digital store we offer a variety of GMC Sierra truck caps by leading brands, such as Bestop, Pop and Lock and other world-known suppliers. We ensure outstanding quality of Sierra products and their affordable prices.
