Unmatched Capability: Towing and Performance

Luxury Meets Utility: The Interior Experience
Inside the cabin, the Sierra 2500HD feels less like a work truck and more like a command center. The 2026 model year introduces even more refinement, especially in the Denali Ultimate trim, which features Alpine Umber leather-appointed interiors and authentic Paldao wood accents.
