A good work truck needs to be strong, reliable, and durable. For those jobs where you need to be pulling heavy loads or moving over uneven surfaces, a heavy-duty truck is essential. That’s where the 2025 GMC Sierra Heavy Duty trucks come in.
Power and Capability
If you want a heavy-duty truck with ample power, the available Duramax® 6.6L Turbo-Diesel V8 engine is for you! This engine gets paired with the Allison® 10-speed automatic transmission. This engine provides a whopping 470 horsepower and 975 ft-lb of torque. Its power comes from the strong turbo vane actuator and the robust valve springs.
For the jobs that require extremely heavy loads, a Sierra Heavy Duty truck is your reliable pickup. The 2500 Crew Cab models offer a maximum towing capacity of 21,870 pounds when properly equipped, while the 3500 Regular Cab offers a maximum hauling capacity of 36,000 pounds when properly equipped. Towing those heavy loads is made much easier with advanced trailering technologies and up to 14 camera views available.
Premium Interiors
All Sierra Heavy Duty trucks promise spacious front head and legroom, so you never have to feel cramped inside your truck. Elevate your comfort even more with 16-way power front seats that have massaging capabilities, as well as a heated steering wheel and dual-zone automatic climate control. Premium materials are on offer as well, whether that’s leather seating or vinyl seat trim.
Stylish Exteriors
Your Sierra Heavy Duty truck is sure to stand out in a crowd with great exterior options, ranging from iconic chrome accents or exterior color choices like Volcanic Red Tintcoat.
