When you're looking at the heavy-duty truck segment for 2026, the Ford Super Duty has some serious momentum, especially when you compare its raw capability and tech updates to what the GMC Sierra HD offers this year. Here how Ford and GMC compete in the heavy-duty pickup segment.
Key Takeaways:
- The Super Duty's changes are largely convenience upgrades, while the Sierra's are minimal and cosmetic.
- The Super Duty's engine lineup offers a wider variety of options and has some of the highest torque ratings in its class.
- The Sierra HD tows up to 36,000 pounds when properly equipped, but does it beat the Super Duty?
What Has Changed for the 2026 Ford Super Duty?
Ford decided to make massive towing jobs a lot less stressful by moving its best trailering tech into the Lariat Premium package. (By making things like Pro Trailer Hitch Assist and Backup Assist easier to get, it's much simpler to manage the truck's 40,000-pound max towing capacity.) Ford also brought back the SuperCab with the 6.5-foot bed and is finally letting buyers pair its high-output diesel with the off-road Tremor package.
The Sierra HD doesn't see much movement for 2026. GMC just swapped out a few paint colors for slightly different shades and made the MultiPro tailgate available on more models.
What's Under the Hood of the 2026 Ford Super Duty?
If you're hunting for the most powerful engine out there, the 6.7-liter Power Stroke diesel is still the one to beat. The standard version gives you 1,050 lb-ft of torque, and the High-Output version steps it up to 500 horses and a class-leading 1,200 lb-ft. If you prefer gas, Ford has you covered with the 405-hp 6.8-liter or the 500-hp 7.3-liter "Godzilla" V8. All mate with a 10-speed automatic transmission and rear- or all-wheel drive.
The Sierra HD's two choices are a 6.6-liter V8 with 401 horsepower and 464 pound-feet, or a 6.6-liter Duramax turbo-diesel that hits 470 horsepower and 975 pound-feet. Both engines use a 10-speed automatic and offer RWD or 4WD, with a dual-rear-wheel axle available if you go for the 3500 HD.
What is the Payload Capacity and Trailering Capacity of the 2026 Ford Super Duty?
The Super Duty is a beast on paper, with an 8,000-pound payload capacity and the ability to tow up to 40,000 pounds with a gooseneck. It handles 35,000 pounds with a fifth wheel and 30,000 with a standard hitch. To keep all that weight under control, Ford added onboard scales with Smart Hitch to check your cargo weight in real-time and help with tongue-weight distribution. There's even Trailer Navigation that picks your route based on how big and heavy your trailer is.
The Sierra 3500HD maxes out at 36,000 pounds if you have the diesel, regular cab, RWD, a dual-rear-wheel axle, and a gooseneck. With a fifth-wheel, it's good for 32,000 pounds. While it doesn't come as a dually in certain setups, it can still pull 22,500 pounds, which is definitely heavy-duty territory.
