The Ford Super Duty dominates the work truck landscape, but the GMC Sierra HD remains a relentless rival that may make you wonder which truck is your best bet on the jobsite. To help you decide, we've broken down the details of both.
Key Takeaways:
- Ford's 2026 updates concentrate on practical utility; GMC's changes for the Sierra mostly focus on aesthetics.
- You'll find a broader engine selection in the Super Duty, along with torque ratings that are among the most impressive in the industry.
- The Sierra HD is a high-performance machine with a 36,000-pound towing limit, but the Super Duty manages to really push the limits of possibility.
By including advanced tools like Pro Trailer Hitch Assist and Backup Assist in the Super Duty's Lariat Premium package in '26, Ford makes these essential features easier to obtain. It also reintroduces the SuperCab with a 6.5-foot bed, and its high-output diesel now pairs with the Tremor off-road package, giving you extreme torque in a truck built for the trail.
The updates for the Sierra 2026 are primarily visual, with a refreshed palette of paint colors to give the truck a new look. GMC has also made the multi-functional MultiPro tailgate available on a larger number of trim levels, bringing its versatile six-position design to more owners.
What Engine is the Best to Choose in the 2026 Ford Super Duty?
For those who need the most muscular engine available, the Super Duty's 6.7-liter Power Stroke diesel is the clear choice. While the standard version is plenty powerful, the High-Output variant produces a staggering 1,200 lb-ft. If gas is your preference, Ford offers a 405-hp 6.8-liter V8 and the 500-hp 7.3-liter "Godzilla" V8. Every engine in the Ford lineup links to a 10-speed automatic. You have the choice of rear- or all-wheel drive.
GMC's powertrain lineup is straightforward but effective. You can choose between a 6.6-liter gas V8 with 401 horsepower and 464 lb-ft, or a 6.6-liter Duramax turbo-diesel, producing 470 horsepower and 975 lb-ft. These engines also pair with a 10-speed automatic and are available in RWD or 4WD, with dual-rear-wheel setups offered on the 3500 HD models.
Is the 2026 Ford Super Duty Good at Towing?
The Super Duty's capability is the rock star in this category, thanks to its massive 40,000-pound maximum gooseneck tow rating. It also rates for 35,000 pounds with a fifth-wheel setup and 30,000 pounds with a standard conventional hitch. These figures represent the ceiling of what is possible in the heavy-duty segment today.
The Sierra 3500 HD is a formidable competitor, but its maximum numbers are a step behind. Its gooseneck towing capacity reaches 36,000 pounds, with the diesel engine, a regular cab, RWD, and the dual-rear-wheel configuration. The GMC can tow up to 32,000 pounds with a fifth-wheel, and its conventional capacity reaches 22,500 pounds.
