When you need a truck to take care of your heavy-duty tasks, the 2025 GMC Sierra HD can be your match. You can choose between two lineups, plenty of cab and bed configurations, and a wide range of trim levels, all of which come well-equipped with performance and comfort features you’ll love.

6 Reasons Drivers Love the 2025 GMC Sierra HD

Impressive Performance

Whether you opt for the Sierra 2500 HD or the Sierra 3500 HD, both lineups come standard with a 6.6L V8 gas engine that produces 401 horsepower and 464 pound-feet of torque. A 10-speed Allison automatic transmission delivers quick distribution of power to the wheels, which means you’ll get plenty of traction and hauling power. A 6.6L V8 turbo-diesel engine is available and a great choice if you need more traction or towing power.


Towing Power for All Needs

The Sierra HD is designed for heavy-duty towing and, depending on the lineup, configuration, and engine, it can tow up to 36,000 pounds. That is more than enough for a huge camper trailer, heavy-duty machinery, and other heavy loads.


Available Dual Rear Wheel Trims

This truck can also haul heavy loads. The base Sierra 2500 HD configuration has a standard payload of 3,907 pounds, but other trim levels can haul up to 4,005 pounds. The Sierra 3500 HD has a maximum payload capacity of 4,721 pounds, and you can choose between single and dual rear wheel setups. Dual rear wheels improve load distribution and performance when transporting heavy items.


Ample Cargo Volume

Regardless of the lineup you prefer, the Sierra HD gives you the choice between various bed options. A great choice for work, the long bed, which is available with all cab styles, provides a cargo volume of 83.5 cubic feet. The Double and Crew cabs also pair with a standard bed that maintains a shorter wheelbase for improved maneuverability and provides a cargo volume of 69.5 cubic feet.


Practical Interior

Whether you opt for the Regular or the Crew cab, this heavy-duty truck boasts a practical interior with easy-to-clean seating surfaces and easy-to-reach controls. Vinyl upholstery is standard on the base trim, while other premium options are available or standard on the upper models. Adjustable front seats allow you to maintain a comfortable driving posture, while under-seat storage and plenty of cubbies provide plenty of in-cabin storage.


On-the-Go Connectivity

Each trim level of the Sierra HD also comes standard with a modern infotainment system that provides intuitive on-the-go connectivity. Android Auto and Apple CarPlay allow you to access numerous phone apps, answer calls, and use your phone’s navigation. Select trims come with Google built-in for added convenience.
