GMC's 2024 Sierra 3500HD is available across a spectrum of trims that lean heavily into luxury as the price climbs. There's a work version, sure. But GMC intends to be The General's luxury truck brand with trims like the new Denali Ultimate that maxes out the options list and nearly hits a six-figure price tag. The 3500HD makes dual rear wheels available (they can't be had on the 2500HD), further increasing its towing and hauling abilities.
Edmunds spotlight: Midcycle update brings new interior, transmission and towing tech
The ever-growing arms race among heavy-duty American trucks continues with updates to GMC's HD lineup this year. Topping the list is a more powerful diesel engine (standard on the new-for-2024 Denali Ultimate trim, optional on other trims) that gains 25 horsepower and 65 lb-ft of torque, bringing it to 975 lb-ft. The base gas engine is now paired with an Allison 10-speed automatic that replaces last-year's six-speed. SLE and higher trims get a 13.4-inch infotainment touchscreen and a 12.3-inch digital instrument cluster. There's an all-new adaptive cruise control system designed to work while trailering as well as new trailering tech enhancements.
Competitors to consider
If you're looking for ultimate towing and hauling capability, there aren't a lot of choices. And if the Sierra 3500HD is at the top of your list then you should also consider the Chevy Silverado 3500HD, which is its mechanical twin. The Chevy costs slightly less and offers different styling and fewer trims. And don't forget about the Ford F-350 and Ram 3500.
2024 GMC Sierra 3500HD trim level differences
The 2024 GMC Sierra 3500HD is a heavy-duty full-size pickup available in six trims: Pro, SLE, SLT, AT4, Denali and Denali Ultimate. It offers four-wheel drive across every trim (it's standard on top trims) and a choice of two engines.
Which Sierra 3500HD trim does Edmunds recommend?
We think the SLT trim hits the sweet spot in terms of value. It offers heated front seats and a heated steering wheel. Four-wheel-drive versions get a two-speed transfer case that will automatically engage the front axle. But it's only available as a crew cab.
The 2024 GMC Sierra 3500HD has a 3 years / 36,000 miles basic warranty and 3 recalls. RepairPal gives it a reliability rating of 3 out of 5, ranks it #14 out of 19 among Fullsize Trucks. Below you’ll find our owner reviews.
