2026 GMC Sierra 2500HD AT4X Crew Cab 4WD

Meet the black 2026 GMC Sierra 2500HD—a used heavy-duty truck that looks as tough as it works. With its deep black exterior matched to a black interior, this Sierra carries a bold, no-nonsense vibe that fits right in whether it’s heading to the jobsite, the backcountry, or just owning the road on the daily commute.

Under the hood sits a 6.6L diesel V8, delivering the kind of confident muscle that makes long grades, loaded days, and wide-open highways feel refreshingly effortless. Pair that with an automatic transmission and you’ve got power that comes on smooth and steady—ready when you are, without fuss.

And because traction matters when conditions don’t cooperate, the 4WD drivetrain is there to help you keep moving when the pavement ends or the weather turns. In true truck fashion, this one’s built around capability and composure, wrapped in a sharp black-on-black package that doesn’t need to shout to make a statement.

For added peace of mind, a CARFAX report is available for this Sierra 2500HD—so you can check out its history before you take the wheel.
