Meet the New Standard for Tailgates.

The 2020 GMC Sierra sets the standard that all other tailgates will be judged by. It's not a stretch to call it the most innovative tailgate ever, revolutionizing accesibility and functionality.

 

Primary GatePrimary Gate Load StopEasy AccessFull Width StepInner Gate Load StopInner Gate With Work Surface
Open the primary gate using the key fob's power release from inside the truck, or from a button the tailgate itself. Once you have the primary gate open, the load stop will help prevent items from sliding out. The inner gate folds down to give you easy access when loading and unloading. The inner gate folds into a large step which holds 375 pounds, making it easy to get into the bed. The inner tail ghate includes a load stop to help prevent items from sliding out of the tailgate. The opened inner gate provides a work suface for you!

The future of the pick up is here, and it's not just the tailgate. To help improve the towing experience with the 2020 GMC Sierra, use the available ProGrade Trailering System and it's companion phone app and HD camera views to make sure you get it right, every time. 

 

GMC didn't just improve the pick up's technology, it improved its safety. Pushing the boundaries of what's possible in a truck, GMC added available HD Surround Vision, Lane Change Alert (complete with Side Blind Zone Alert) and much, much more.
