Like every truly American full-size pickup truck, the GMC Sierra features excellent payload capacity and a strong frame. However, this truck was crafted as a luxury-oriented vehicle, so it became an ultimate combination of the convenience of an executive vehicle and reliability and functionality of a pickup. The Sierra appeared in 1987 and is available on the market up to the present day. A wide range of luxury options attracted the buyers’ attention to the vehicle, so by 2000, the automaker introduced the most upmarket trim level and called it the C3. This version of the truck came with a luxurious interior and upscale steering system. Two years later, the name of this configuration was changed to the Denali.

If you use your Sierra for business purposes or simply from time to time have to transport something oversized in your truck, think of extra opportunities you may get by extending the truck’s bed. It is curious that you will not have to do any major modifications to the bed of your vehicle and may easily remove the extender, when you do not need extra space or simply want to close the tailgate. To review the complete assortment, you are welcome to check out our catalog of GMC Sierra bed extenders, crafted to perfectly fit your vehicle.
