If you’re looking for a heavy-duty pickup truck that can handle even the toughest tasks, the 2025 GMC Sierra HD is your perfect work companion. Available in 2500 HD and 3500 HD models, the Sierra HD offers both gas and diesel engine options to suit your unique needs and worksite demands.
Powerful Performance: Meet the Ground-Trembling V8
The Sierra HD’s base engine is a 6.6L V8 gasoline engine, delivering an impressive 401 horsepower and 437 lb-ft of torque. It comes equipped with an Allison 10-speed automatic transmission and Auto Grade Braking, which ensures a smooth, controlled descent when driving downhill. On the 3500 HD model, this engine provides a maximum payload rating of 4,571 lbs, making it ideal for heavy-duty hauling.
For even more power, the Sierra HD can be upgraded to the 6.6L Duramax turbo-diesel V8 engine. This powerhouse produces an astounding 470 horsepower and 975 lb-ft of torque, allowing it to tow up to 36,000 lbs when properly equipped. Whether you’re hauling equipment or towing a large trailer, the Duramax engine has you covered.
Innovative Tailgate Options for Easy Loading and Unloading
The standard locking tailgate on the Sierra HD makes loading and unloading a breeze, swinging down to provide a flat surface. For added convenience, you can opt for the available GMC MultiPro Tailgate, which offers six different functions. These features include the ability to lower the tailgate fully, fold it into a box step for easy access, or extend the inner gate to form a load stop. Additionally, the MultiPro Tailgate can even be folded into a workbench, giving you a versatile solution for any task.
Built Tough for Any Job
When it comes to durability, the Sierra HD is built to last. Both the 2500 HD and 3500 HD models are constructed with high-strength steel frames, including hydroformed front sections, to ensure maximum durability and strength. The truck bed is made from rolled-formed steel, providing the toughness required for heavy hauling without compromising long-term reliability. The Sierra HD’s standard suspension package is equipped with rugged shocks, designed to maintain a smooth, comfortable ride even when carrying heavy loads.
Trailering Technology That Makes Your Job Easier
The 2025 GMC Sierra HD is packed with innovative trailering technology to make hauling and towing more efficient. With 13 available camera views—including a transparent trailer view and bird’s-eye view—you’ll have all the visibility you need to tow with confidence, even in tight urban spaces. The ProGrade Trailering System offers intuitive assistance for hitching, while the In-Vehicle Trailering App provides a pre-departure checklist, trailer security alerts, and much more. All of these features are easily accessible through the truck’s 13.4-inch touchscreen or your smartphone, helping you stay organized and in control throughout your workday.
