As winter slowly slips into spring and eventually summer, there’s no better way to make the most of the season than getting out on the water with a boat in tow. The 2026 GMC Yukon and Yukon XL are two of the most capable full-size SUVs on the market, with maximum towing capacities of up to 8,400 pounds (3,810 kilograms) when properly equipped. The towing capacity varies depending on which engine, drivetrain, and package you choose. Here's a complete breakdown to help you find the right configuration before you visit us at Terra Nova Buick GMC in St. John's.

What Affects Towing Capacity?

Three factors move the needle most on the 2026 Yukon: engine choice, drivetrain (2WD vs. 4WD), and whether you opt for the available Max Trailering Package (RPO code NHT). In general, 2WD configurations tow more than their 4WD counterparts due to weight differences, and the NHT package unlocks the highest ratings across the board. The turbodiesel 3.0L I6 is worth a special mention. It holds its numbers very consistently across 2WD and 4WD, making it a strong choice if you want predictable, high-capacity towing regardless of drivetrain.

2026 GMC Yukon XL Towing Capacity

The Yukon XL's slightly lower figures across the board are expected. The extended wheelbase and additional body length add weight, which eats into max trailer ratings. Note that the NHT package is not available on the Duramax diesel.

Which Engine Is Right for You?

• The 5.3L V8 is the most flexible option. It's available across the widest range of configurations and, with the NHT package, reaches the highest towing rating in the Yukon lineup at 8,400 pounds.
• The 6.2L V8 delivers more power but trades a small amount of towing capacity for it, making it better suited for drivers who prioritize performance alongside capability.
• The Duramax 3.0L I6 turbodiesel is the standout for sustained highway towing — it achieves its strong numbers without needing the NHT package, and its torque characteristics make it ideal for long hauls on routes.
