　　Today's crop of full-size trucks are plenty capable for most users, but for the select few who need to tow and haul even more, heavy-duty trucks are the way to go. The 2024 Sierra 2500HD is the first rung in GMC's heavy-duty lineup, supporting the even more capable 3500HD. When this Sierra HD generation debuted four years ago, it lagged behind rivals in towing capacity and interior quality, but improvements along the way have largely evened the playing field. Within that field, the GMC Sierra is positioned as a more luxurious version of the related Chevrolet Silverado 2500HD.

zzdcar spotlight: Big upgrades for 2024

With heavy-duty pickups, capability is the name of the game, and for 2024 the GMC Sierra 2500HD receives upgrades that finally make it competitive against other trucks in the class. Power from the optional diesel engine rises to 470 horsepower and 975 lb-ft of torque. GMC says the engine offers 25% more low-end torque compared to last year. The gasoline engine also upgrades to a 10-speed transmission, replacing the previous six-speed. These result in an increase in conventional towing to 21,900 pounds for crew-cab models and 22,500 pounds for regular- and extended-cab models. Off-road enthusiasts will appreciate the new AT4X trim that builds on the returning AT4 model, while the new Denali Ultimate trim pushes luxury even further.

　　

Competitors to consider

With towing capabilities now comparable to other heavy-duty trucks, the 2024 GMC Sierra 2500HD is on more solid footing. It's more expensive than the related Chevrolet Silverado 2500HD but also notably more luxurious. We're partial to the Ford F-250 Super Duty, which was redesigned last year. It benefits from a wealth of new technology, including worksite apps and tools. The Ram 2500 is another favorite, with a smooth ride and a cabin similar to the GMC in premium design and materials.

　　

Which Sierra 2500HD does zzdcar recommend?

For most people, we recommend the midrange SLT trim. It adds several features that dress up the interior and improve capabilities, making it feel much more polished than the rather spartan lower trims.

　　

GMC Sierra 2500HD models

The 2024 GMC Sierra 2500HD is a heavy-duty pickup truck available in two-door regular-cab, four-door extended-cab (Double Cab) and four-door crew-cab configurations matched with the standard 6.8-foot or the long 8.1-foot cargo bed.

　　Seven trim levels are available. The Pro is the basic work truck, and the SLE builds on that with an upscale look and added equipment. Choose the SLT trim for leather and other premium amenities, the AT4 or new AT4X if off-roading is a part of your plans, or the Denali and new Denali Ultimate for the most luxurious versions of the Sierra 2500HD.

　　Additionally, GMC offers a choice between two engines, one gas and one diesel. A 6.6-liter gasoline V8 engine (401 horsepower, 464 lb-ft of torque) is standard, paired with a 10-speed automatic transmission. A turbocharged 6.6-liter diesel V8 engine (470 hp, 975 lb-ft) is optional and also uses a 10-speed automatic. Four-wheel drive is optional for the Pro, SLE and SLT, and it comes standard on the AT4 and higher trims.
