GMC Sierra HD

Improved design for unwavering performance

Driving off-road is important for many truck owners — including those here in Shelby County, Tennessee. That’s why GMC aimed to improve the 2024 Sierra HD’s aptitude for all-terrain performance. You no longer have to choose between off-road tuning or towing capabilities; engineers gave the 2024 GMC Sierra HD the best of both worlds. The result is a heavy-duty truck with balanced, stable handling whether driving on or off the pavement.

Off-roading enhancements of AT4X

Following the high praise garnered by the Sierra 1500 AT4X and Canyon AT4X, the Sierra HD is the next GMC model to receive the AT4X treatment. The 2024 Sierra HD AT4X leans into the truck’s all-terrain potential by equipping it with elite products to conquer rough landscapes. These include a 1.5-inch factory-installed lift, Multimatic DSSV dampers, rear e-locking differential, larger underside plates, and mud tires.

Activate its exclusive Off-Road Mode to let the truck automatically adjust its settings based on the ever-changing topography. The Sierra 1500 AT4X will intuitively know how best to tweak the motor, traction, and suspension based on its readings of the land.

Go wild with the Extreme AEV Edition

Take the Sierra HD AT4X beyond its limits by adding exclusive enhancements to the Extreme AEV Edition. By partnering with AEV, GMC can give your 2024 Sierra 1500 the best factory-installed off-roading equipment in its catalog. The heavy-duty truck won’t flinch from bumps or bruises when it’s shielded by AEV thick-steel skid plates, stamped steel bumpers, and tougher wheels.

Diesel does it better

Pick your preferred performance powerhouse: either the standard 6.6-liter V8 engine (gas or FlexFuel) or the turbocharged Duramax™ version of the 6.6-liter V8.

Based purely on the numbers, we think you’ll prefer the Turbo-Diesel. Why? GMC enhanced it this year, raising its output to a whopping 470 horsepower and 975 lb-ft of torque. This allows the 2500HD to tow up to 22,070 pounds and the 3500HD to tow up to 36,000 with the right equipment and configuration. Even the AT4X can trailer up to 18,500 pounds, letting you take your machinery through your field with ease.

Your new favorite features

The best HD trucks prove that towing prowess is about smarts as much as strength — and the 2024 Sierra HD excels in both ways. This year, GMC gives the 2500HD and 3500HD the most trailering assistance technologies of any heavy-duty truck.

A highlight is the ProGrade™ Trailering System that lets you check trailer lights, customize settings, view up to 15 different camera angles, and access information via your smartphone — all from the in-cab touch screen. Driving assistance systems like Adaptive Cruise Control and Side Blind Zone Alert can be upgraded to account for a trailer hitched behind you.

The latest tech and luxury upgrades

The 2024 Sierra HD still embodies the premium quality and refinement of the GMC brand; it can be outfitted with an array of comfort and convenience features to elevate your most stressful days. Seat memory settings and remote engine start will get you situated in a hurry. The MultiPro™ Audio System by Kicker and wireless phone projection make your time at the worksite more enjoyable. Go digital with the 12.3-inch configurable driver information center and 15-inch-diagonal head-up display always within view.

You’ll find all of the Sierra HD’s top luxury enhancements in the truck’s first-ever Denali Ultimate trim. Laser-etched Paldao wood, full-grain leather, embossed patterns in the cab, metal badging, and LED lighting animation show how stunning the Sierra HD is when dressed to the nines.
