Power is the name of the game when it comes to the GMC Sierra 3500HD. And to say it can haul and tow a lot of weight would be an understatement.

With its high level of power and luxury, the GMC 3500 HD is a solid full-size pickup truck that's well worth your time and money.

What's New For 2024?

The 2024 GMC Sierra 3500HD is getting a midcycle refresh for the new model year. Some changes include a revised front fascia with newly available LED headlights and taillights with sequential turn signals. Among the more significant changes are a revised powertrain with more towing capacity and an all-new trim.
The new trim, the Denali Ultimate, offers greater luxury than the Denali tier, adding leather-wrapped door panels, steering wheel, and 16-way power-adjustable front seats. The front seats also have intricate leather stitching and offer heated and cooled messaging.
As for the powertrain update, GMC is enhancing its Duramax turbocharged diesel V-8's power and torque. Now this powertrain can output 470 horsepower and 975 pound-feet of torque, respectively. With the increase in power, the towing capacity for models with this engine has increased to 22,500 pounds.
Additional changes include replacing the gas-powered V-8 with an Allison-certified 10-speed automatic transmission and adding more standard driver-assist features.

Interior/Exterior

The 2024 GMC Sierra 3500 HD offers a commanding exterior presence and a spacious and luxurious interior. When looking at its exterior, Middleborough residents may first notice the model's bold LED headlights, a prominent grille, and slick sculpting that help define its look.
In the cabin, the more refined materials and meticulous details will catch most occupants' eyes. The comfortable seating, and use of high-quality finishes, make the interior a well-crafted model and offer one sophisticated driving experience.</p>

Performance

Standard under the hood of the 2024 GMC Sierra 3500HD is a gas-powered 6.6-liter V-8 that generates 401 horsepower and 464 pound-feet of torque. This engine pairs with a 10-speed automatic transmission and rear- or four-wheel drive.
For even greater power, Duxbury drivers can purchase the new optional Duramax diesel 6.6-liter V-8 that outputs 470 hp and 975 pounds of torque. This powertrain will use an Allison-certified 10-speed automatic transmission and can be mounted under a single- or dual-rear-wheel axle.
With this much power, it's no wonder the Sierra 3500 HD is such a powerhouse. When properly equipped with a diesel engine, regular cab, rear-wheel drive, dual-rear-wheel axle, and a gooseneck hitch, this pickup can carry its max payload of 36,000 pounds. Though with only a fifth wheel hitch, the capacity drops to 32,000 pounds.

Technology

Every 2024 GMC Sierra 3500HD has a touchscreen infotainment system with Apple CarPlay and Android Auto. Base models offer a seven-inch display with dual USB jacks and rotary knobs, and physical buttons that are easily accessible.
The larger eight-inch touchscreen can be upgraded with built-in navigation, a Bose audio system, SiriusXM satellite radio, and a rear-seat entertainment system. With the massive 13.4-inch monitor, Plymouth shoppers will get features like Google Built-in and split-screen navigation.
Other features include a smartphone app that remotely controls trailer functions and different trailer profiles allowing users to store data to monitor maintenance.
