The 2026 GMC Sierra HD has undergone significant upgrades in its off-road capabilities, making it a formidable force in challenging terrains.
The suspension system has been completely redesigned, featuring upgraded components and enhanced geometry.

The 2026 GMC Sierra HD boasts impressive towing and payload capacities, outperforming its predecessor and many competitors in its class.
The maximum towing capacity of the Sierra HD has increased significantly, now reaching up to 36,000 pounds for fifth-wheel and gooseneck towing. This represents a notable improvement over the previous model’s maximum towing capacity of 30,000 pounds.
Similarly, the Sierra HD’s maximum payload capacity has also increased, now reaching up to 7,290 pounds. This is a substantial increase compared to the previous model’s maximum payload capacity of 6,500 pounds.
