2023 GMC Sierra 1500 AT4X

More Power. More Capabilities. More Fun.

The 2023 GMC Sierra 1500 AT4X offers premium off-road adventures in America's most dependable full-size truck. 

The Sierra gives you the power to take this beast to the limits. It features a second-generation 3.0L Duramax Turbo-Diesel engine. This second generation features some impressive upgrades over the first, including new steel pistons with a revised combustion bowl, retuned turbo compressor, new fuel injectors, and improved temperature control features. 

The AT4X comes equipped with everything you need to get off-road, but with all the luxuries you demand. It is ready to hit the desert with the AEV stamped-steel front bumper with front winch capability. The uniquely tuned springs increase maximum front and rear suspension travel. It comes standard with off-road chassis and tuning, front and rear e-locking differentials, and features the new Terrain Mode for low-speed, off-road conditions. 

You'll be ready to hit the dirt with the 33" Goodyear Wrangler Territory mud-terrain tires. The optional AEV hot-stamped boron steel skid plates protect your investment while you tackle the hardest off-roading challenges.

But you don't have to give up comfort to get the rugged features with the GMC Sierra 1500 AT4X. The luxurious interior features 16-way power front seats with massage feature. The full-grain leather seats and leather-trimmed instrument panel in Vanta ash wood trim is a sweet offset to the Obsidian interior and red and white double-needle stitching on the seats. 

The 12-speaker Bose Premium Series with Counterpoint Surround Sound pairs beautifully with the GMC connected services. The 13.4" color touch screen infotainment system with Google built-in compatibility puts everything at your fingertips. 

Passengers enjoy heated front and rear seats, ventilated front seats, and a 60/40 folding bench seat in the back with additional storage. 

Handling cargo has never been easier with the six-function MultiPro tailgate that makes climbing in and out a breeze. An optional trailer package includes trailer hitch and connectors. A Hitch Guidance Integrated trailer brake controller is available.
