About This Vehicle
This 2025 GMC Sierra 2500HD Denali Ultimate is the pinnacle of heavy-duty luxury, with under 4,000 miles and finished in sleek Sterling Metallic over a premium Alpine Umber interior. As bold as it is capable, this Denali Ultimate delivers serious power with its 6.6L Duramax turbo-diesel V8 and 10-speed Allison transmission—engineered for towing, hauling, and commanding the road with ease.
Inside, the cabin is nothing short of first-class, featuring full-grain leather, open-pore wood trim, and advanced tech like a 13.4-inch touchscreen, digital driver display, and head-up display. Heated and ventilated massaging front seats, a premium Bose sound system, and refined detailing throughout make this Sierra as comfortable as it is capable. With striking looks, near-new mileage, and top-tier features, this Denali Ultimate is built to impress on every level.
