Pros can’t be confined. Not with nearly 4 million square miles of the U.S. begging to be explored. The Next Generation Sierra Heavy Duty invites you to pull your world with you. Get out there in the premium-packed Sierra HD Denali or for road trips without roads, the First Ever Sierra HD AT4. Go explore the world—without leaving yours behind.
Experience the heavy-duty truck for you—the Next Generation 2020 GMC Sierra Heavy Duty.
Redesigned with larger and bolder proportions (up to 2" taller, 10" longer and 1" wider than the previous generation), the Next Generation Sierra Heavy Duty pickup truck was built big so you can tow big.
A refined cabin offers advanced technology to help ensure a comfortably smart ride in this heavy-duty truck.
Open the primary gate using the key fob’s power release from inside the truck or from a button on the gate.
