2023 Sierra 3500 HD AT4

Heavy-duty off-road trucks need to impress with power, size, and capabilities. Fortunately, GMC has delivered with the 2023 Sierra 3500 HD AT4. It brings a mix of rough and rugged features combined with technology and comfort to ensure you have a top driving experience.

Let’s find out why the new release will impress drivers in 2023.

Power and Capabilities

The Sierra 3500 HD AT4 is built for trailering, towing, and carrying a heavy load. The 3500 model offers impressive stats for handling whatever you need. That includes a 9,072kg trailering capacity, a 9,584kg gooseneck hitch, and a 1,903 kg maximum payload.

For those trips off-road, different features work together to help you handle each challenge in comfort. The high-strength chassis is an asset for all activities, and the skid plates, Eaton locking rear differential, and Rancho shocks protect the truck and give you traction. Plus, the 284mm ground clearance will give you peace of mind on more challenging terrain.

The Sierra 3500 HD AT4 has independent front suspension and rear springs to balance payload, which provides superb ride quality. In terms of power, you can choose the 6.6L V8 gas engine with the six-speed transmission or the 6.6L Duramax V8 turbo-diesel with Allison 10-speed transmission.

Pricing and Options

The 3500 is the powerhouse of the 2023 Sierra HD AT4 options. Once you choose that model, there are still trim options available to you to get the exact vehicle you need. It comes with 4WD and a crew cab, and prices start at $81,603.

One of the key choices to make is whether to stick with the standard 2.1m truck bed or opt for 2.4m. Your use of the truck might mean that an additional package is right for you. The X31 off-road package gives you that off-road suspension for uneven terrain. Whereas the fifth wheel/gooseneck hitch package fits you with a hitch platform and trailer harness.

Besides the practical packages, you’ve got options for the overall finish. The 3500 AT4 comes with 45.72cm all-terrain tires as standard, but a 50.8cm high gloss black aluminum fit is also available. For a quick upgrade on appearance and tech, there is the AT4 Preferred or AT4 Premium Plus packages.


Convenience and connectivity weren’t forgotten. This heavy-duty truck has 15 camera views available, including HD Surround Vision, a bed view camera, and the choice to switch between a traditional rearview mirror and a camera view.

The indoor sound system is fantastic, with Apple CarPlay, Android Auto, and superb connectivity. There are also options to bring your music outdoors via the tailgate with the MultiPro Audio System by Kicker.

A Slick and Safe Ride

With advanced safety alerts, a suspension built for whatever you need your truck to do, and incredible power, the 2023 Sierra 3500 HD AT4 delivers a ride like no other. Start your adventure today!
