Starting at
When it comes to a heavy-duty truck, power matters. Choosing a vehicle like the 2024 GMC Sierra 3500 HD means you are looking for something with some bite. An average truck won't do; instead, you need something above average, which is exactly what the Sierra 3500 HD is.
The 2024 GMC Sierra 3500 HD comes standard with a 6.6-liter gas V8 engine, but there isn't anything basic about it. Direct fuel injection means less wasted fuel, which equates to better fuel efficiency and more power. The overhead valve design offers better torque optimization in the lower RPM range so your truck can handle oversized loads from the start. The 6.6-liter V8 cranks out 401 hp and 464 lb-ft of torque, making it perfect for heavy-duty needs.
Some jobs call for the "big guns," which is where the Duramax 6.6-liter V8 turbo-diesel comes in. The turbo-diesel is a common-rail high-pressure fuel injection engine, which has several advantages. Better gas mileage, increase in power, and a quieter engine are a few benefits that can be expected. The design seriously boosts performance, offering 470 hp and a mind-blowing 975 lb-ft of torque early in the RPM power band.
Both engine options are paired with the impressive Allison 10-speed automatic transmission. The Allison transmission is designed to work with the engine's torque and power band to make sure you get as much possible power when you need it the most. Experience your truck the way it should be, with more control to tackle towing, hauling, off-roading, and more.
When properly equipped, the 6.6-liter gasoline V8 has a payload capacity of 7,290 lbs. The turbo-diesel is a smidge less due to the added weight of the diesel engine and can handle up to 6,644 lbs. When trailering, the gas engine has a maximum capacity of 18,800 lbs for conventional towing and 19,150 lbs for fifth-wheel and gooseneck trailering. For more muscle, the diesel engine maxes out at 20,000 lbs conventionally and 36,000 lbs for gooseneck and fifth-wheel trailers.
The 2024 GMC Sierra 3500 HD is more than meets the eye, with best-in-class trailering assistance technologies. Plus, with the addition of the ProGrade Trailering System, the Sierra HD offers the most trailering tech in the heavy-duty truck class. Select technologies have been enhanced to better handle gooseneck and fifth-wheel trailering so that you have improved coverage no matter what you are towing.
An exhaustive camera system offers up to 14 camera views so that every angle is covered. To help with hitching your trailer, the camera system includes a Hitch View angle with the addition of Hitch Guidance. This provides a close look at the receiver hitch and provides onscreen guidance lines to help you line up to the trailer.
A Rear Camera Mirror turns your typical rearview mirror into a live camera feed offering unobstructed views. With an optional camera placed in your trailer, you can gain access to an Inside Trailer View that lets you monitor your cargo. There is even a Cargo Bed View that allows you to zoom in to check on cargo in the box or to hitch a gooseneck or fifth-wheel trailer.
Driving with a trailer attached can be difficult, especially when you are trying to maneuver on city streets or highways. That's why the available Rear Side View with Trailer Length Indicator is such a helpful tool. This camera view looks down the length of your trailer, highlighting traffic alongside your trailer to make changing lanes easier and safer.
Some tech is so advanced it almost seems like magic, which is the case with the Transparent Trailer View. This option takes several camera angles and combines them to create an amalgamation that allows you to "see through" your attached trailer. The tech isn't new, but it has been enhanced for the 2024 model year and is now compatible with gooseneck and fifth-wheel trailers. This is an industry first, providing more options than ever before.
A long time ago, when trucks first roamed the Earth, the interior was often overlooked. However, that is no longer the case. Now trucks are just as much leisure vehicles as they are work vehicles, paying as much attention to the design of the vehicle as its functionality. The interior of the 2024 GMC Sierra 3500 HD stands out as a getaway meant to optimize comfort.
With the exception of the Pro trim, all Sierra trims have been given an updated and refreshed interior. Choose between either Jet Black or Dark Walnut/Slate for the SLE and SLT. One offers durable cloth upholstery, while the other includes perforated leather appointments. There are options to upgrade the front seats, including features like ventilation, heating, and power adjustment.
If you want rugged luxury, the AT4 trim has it all. Heated and ventilated power-adjustable front seats come standard. The interior includes leather detailing in a unique color combination of Jet Black with Kalahari trim. Heated rear seats and a heated steering wheel seal the deal.
For a richer interior, the Denali offers forge-perforated leather seating in two decadent color combinations: Jet Black or Atmosphere/Brownstone. Aluminum and chrome accents give the warm tones a brightness that brings it into the modern day, while real wood trim keeps it down to earth. Distinct Denali etching shows off your truck with pride. This premium interior provides a luxurious place to sit back and relax no matter how long the trip takes.
Of course, if you really want to enjoy the finer things in life, then you have to take a look at the most luxurious heavy-duty pickup around. The very first Denali Ultimate takes everything you love about the Denali and hypes it up to offer the most opulent Sierra HD interior to date. The Denali Ultimate is decked out in full-grain leather upholstery embossed with a pattern representing Mt. Denali. This unique design creates a fascinating look that is present throughout the cabin.
The Denali Ultimate interior is upholstered in Alpine Umber and uses stitching to accentuate the styling. Paired with real Paldao wood trim, the cabin is lush and welcoming. Microsuede is also used to add another texture to the mix. A premium sound system, incredible massaging seats, and Denali Ultimate badging finish it off.
