New Denali Ultimate and AT4X trims debut
Part of the fourth Sierra 2500HD generation introduced for 2020

Overview

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.

Cost to Drive^{Cost to drive estimates for the 2024 GMC Sierra 2500HD Denali Ultimate 4dr Crew Cab 4WD SB (6.6L 8cyl Turbodiesel 10A) and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of N/A undefined in Ohio.}

Edmunds 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 Edmunds 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.

2024 GMC Sierra 2500HD Denali Ultimate 4dr Crew Cab 4WD LB (6.6L 8cyl Turbodiesel 10A)

I purchased and still have a 2024 GMC Denali Ultimate that I have had nothing but issues with since the second week of purchasing new. The truck left me and my family stranded in Walsenburg Colorado with only 1,253 miles on it. We called On Star to have a wrecker take it to the dealer. On Star wouldn’t send a wrecker because we had a 22’ utility trailer so we where out a wrecker bill. I …

In my opinion, I would steer clear of this truck. I purchased a 2024 GMC 2500 Denali Ultimate in April 2023, and it's been nothing but trouble since. The truck has spent over 90 days in the shop, yet they still haven't managed to resolve all the issues.

2024 GMC Sierra 2500HD Denali Ultimate 4dr Crew Cab 4WD LB (6.6L 8cyl Turbodiesel 10A)

Totally disappointed with the truck, Has been beck to the dealer 3 times in the 6 months I have had it. Don't spend the money isn't worth it, bad fuel mileage, GPS and Satellite radio lose signal all the time, the transmission doesn't shift correctly. Had my previous Denali for 8 years no problems , the new one is disappointing!

GMC Sierra 2500HD vs. Ford F-250 Super Duty

Coming off a full redesign last year, the Ford F-250 is the heavy-duty pickup to beat in the class. With a conventional hitch capacity of 20,000 pounds to match the Sierra and a fifth-wheel/gooseneck capacity up to 23,000 pounds, the F-250 holds a slight towing advantage. In terms of technology, the Ford has an edge, offering 5G capability and several useful tools and apps for worksites.

GMC Sierra 2500HD vs. Ram 2500

The Ram 2500 also matches the Sierra's 20,000-pound conventional two capacity and finds a few advantages in regard to comfort, interior and technology. Ram uses a coil-spring suspension, which delivers a smoother and more comfortable ride, especially when the bed is unloaded. Its interior is more luxurious than the competition, rivaling the GMC's Denali trims. Add in the handy RamBox bedside bins and it's hard to turn away from the Ram.

GMC Sierra 2500HD vs. Chevrolet Silverado 2500HD

The Sierra and Silverado are nearly identical underneath their bodywork, with similar capabilities and manners on the road. The Chevy isn't as luxurious or refined as the GMC, but it's also not as expensive. That places the Silverado as a better truck for job-site duties, while the Sierra could be thought of more as a foreman's or manager's rig.

2024 GMC Sierra 2500HD First Impressions

byNick Yekikian

•10/11/2022 (updated 5/01/2023)

What is the Sierra 2500HD?

The GMC Sierra 2500HD is, as the name implies, the heavy-duty version of the GMC Sierra 1500. GMC's offerings in the truck segment present as more luxurious alternatives to their Chevrolet Silverado cousins, though there's generally less variety in the GMC lineup compared to the Chevy equivalents. But GMC's own Denali sub-brand is proof enough that buyers are willing to spend big bucks on big trucks, and it's in the automaker's best interest to capitalize as much as possible.

To that end, GMC is launching a new model for the 2024 Sierra HD. It's called the AT4X, and it's aimed squarely at customers who want to do anything and go anywhere without sacrificing comfort. It doesn't look all too different from the standard 2500 models, but it has a (very) slightly different front fascia and AT4X badging to help it stand out.

Beyond the minor cosmetic changes is some new off-road ready hardware. The AT4X starts with a 1.5-inch lift for better ground clearance, an electronically controlled locking rear differential and 35-inch Goodyear Territory all-terrain tires. Other more detailed hardware changes include new upper and lower control arms for the front end, a larger steel skid plate to protect the transfer case and an aluminum skid plate at the front. That's all good, but the biggest news is the addition of Multimatic DSSV dampers, which replace the twin-tube Rancho shocks of the AT4. The advantage of DSSV dampers is, essentially, greater tuning variability to control damping. The result is more precision and better control both on- and off-road — and it's the same suspension setup used in the recently announced Silverado HD ZR2.

For those who want to take the HD AT4X to 11, there's the Extreme AEV edition. It further adds stamped steel bumpers and heavy-duty steel skid plates, plus the AEV's 18-inch Salta wheels (wrapped in the same Goodyear tires) and unique exterior badging.

The AT4X will be offered with gasoline and diesel engines. The former is a 6.6-liter gasoline V8 that makes 401 horsepower and 464 lb-ft of torque, while the turbocharged 6.6-liter V8 diesel makes 470 horsepower and 975 lb-ft of torque. Both engines are mated to a 10-speed Allison automatic transmission. Max conventional towing for the AT4X is rated at 18,500 pounds should you opt for the standard AT4X with the diesel engine. Gas-powered AT4X models can tow up to 16,000 pounds. Gooseneck trailering is rated at 18,000 pounds for the gas AT4X and 17,300 pounds for the diesel.

The cabin is exactly what we've come to expect from GMC: a slightly zhuzhed-up version of the Silverado's interior. There's an exclusive color scheme called Obsidian Rush and, as you might imagine, it's all blacked-out. It also includes massaging full-grain leather seats, a 12-speaker Bose sound system and wood decor. The dashboard is dominated by the 13.4-inch infotainment display we've seen in other Sierras and is partnered with a 12.3-inch customizable digital instrument cluster and 15-inch head-up display.

Edmunds says

This reminds us a lot of the Silverado ZR2 that was just announced, and when the GMC hits dealers in the fall buyers will be faced with a choice of two trucks that are quite similar. But as the saying goes, choice is its own luxury.
