What Difference This Trim and Others
The GMC Sierra 3500 Denali Ultimate sits at the very top of the Sierra 3500 lineup, focusing on maximum luxury and refinement.

While the standard Denali offers many upscale elements, the Denali Ultimate goes further with massaging seats, a superior audio system, and additional high-end amenities. For U.S. buyers who want the most luxurious heavy-duty truck experience without sacrificing towing or payload capacity, the Denali Ultimate provides the ultimate combination of prestige and power.
