If off-roading is something that interests you, that means that having a powerful piece of machinery to facilitate adventures is a top priority. What happens when one of the most respected brands to ever produce trucks adapts off-roading performance to a vehicle with a reputation for towing and hauling thousands of pounds? You get the 2024 GMC Sierra 2500 HD and its AT4 and AT4X trims. Aside from offering unbeatable power and performance that’s ideally suited for off-road adventure, you can customize your own and build an off-road vehicle that is an extension of your individuality—one that displays your love for personal freedom. Here at Jim Ellis Buick GMC Mall of Georgia, we’re more than just a GMC Sierra 2500 dealer—we’re the outfitters for your next expedition. Buckle up—we’re about to go where the pavement ends, and things get really interesting.

The Basics of the AT4 and AT4X Trims

While the capabilities of the GMC Sierra 2500 HD in the realm of towing and trailering and completing the big jobs are well known, the AT4 and AT4X trims usher the vehicle into a new phase in its legacy—complete and total off-road domination. The AT4 has a suspension designed for off-roading with twin-tube shocks from Rancho and 20-inch gloss aluminum wheels. The AT4X includes a broader range of features that are meant for the off-roader who sees off-roading as a lifestyle and not just a hobby. A lifted suspension, 35-inch all-terrain tires, DSSV dampers, and a locking rear differential check all of the boxes in terms of everything that an adventurer craves. When it comes to the roadblocks and obstructions that might have blocked your path at one point, they’re now a thing of the past, thanks to the elevated ground clearance that measures out beyond eleven inches. If you have as strong an interest in towing and trailering as off-roading, you’ll be pleased to know that you’ll have a maximum towing capacity of 18,500 lbs.

Start Your Engines!

Before you can start conquering new terrains and exploring new frontiers, you’ll need to pick the right powertrain for the job. The AT4 and AT4X trims have two engines that are ready to tackle off-road challenges. Both engines pair with a ten-speed automatic transmission for optimum performance. The standard offering for both trims consists of a 6.6L gasoline-fueled V8 engine. With 401 hp and the capacity to generate 464 lb-ft of torque, the base powertrain is anything but basic. For those who crave a higher level of performance, a 6.6L Turbo Diesel V8 from Duramax is available. With its incredible ability to crank out 975 lb-ft of torque and 470 hp, it is proof that diesel is just as viable now as it ever has been.

Available AT4 Packages

In order to customize your off-roading experience, GMC offers a variety of packages for both trims that can enhance the experience behind the wheel as well as facilitate the adventures that you’ve always wanted to embark on. Which package is best for you depends on what those adventures look like.

AT4 Preferred Package

Just because you’re embarking on an adventure doesn’t mean you have to forgo the amenities and technological innovations that the modern vehicle is known for. The AT4 Preferred Package includes a rear sliding power window, LED roof markings, and a universal home remote. It also adds adaptive cruise control to increase reaction time by adjusting traffic patterns during long stretches of highway driving on your way to or from the trail.

Technology Package

Meant to enhance your driving experience even further, this includes a rear-camera mirror and also includes the items from the AT4 Preferred Package. You’ll also have the additional benefit of a 15-inch head-up display.

AT4 Premium Plus Package

This is for off-roaders who want it all. This package includes all of the features from the two previous packages, as well as a power sunroof and high clearance side step.

AT4X AEV Edition Package

The packages that are available on the AT4 are also available on the AT4X, but only the latter of these two has a trim-specific package that takes off-road mastery to the next level of capability and prowess. This package contains a number of style upgrades, such as AEV branded floor liners, head restraints, and stamped steel front and rear bumpers. Some of the upgrades to the body of the vehicle that enhance the off-roading experience include 18-inch wheels, skid plates that protect the front approach, steering gears, and a transfer case. Just because you’re someone who plays in the dirt doesn’t mean that you can’t look awesome while doing so.

Custom Sierra Styling

The exterior of what we drive is the first thing people see, and making a first impression is something that the Sierra is extremely good at. The AT4 and AT4X have six available shades of red, black, and gray—Titanium Rush Metallic, Thunderstorm Gray, Onyx Black, Sterling Metallic, Volcanic Red Tintcoat, and Titanium Rush Metallic. If you decide to custom-order a brand-new AT4 or AT4X, you can call the shots about what the outside of your truck looks like.

The Advantages of Custom Ordering Your GMC Sierra 2500 AT4 or AT4X

Custom ordering your vehicle has some enticing qualities, such as getting a vehicle that’s built to your precise specifications. But there’s another advantage that you might not have thought about. In 2020, while the world was preoccupied with other things, another event took place that we’re still dealing with. Due to an unforeseen combination of circumstances, there’s still a worldwide microchip shortage. This has had an adverse effect on industry around the world, and the automotive industry in particular. Car and Truck production quotas have been limited, and some items can only be produced in limited quantities. Custom ordering your vehicle not only ensures that you get the features you want but also places your choices as a priority so you can get behind the wheel of your AT4 or AT4X sooner.
