Dealer notes
The Duramax 6.6L turbo-diesel under the hood is the starting point, but what sets this 2026 GMC Sierra 2500HD Denali Ultimate apart is how completely it bridges a heavy-duty work truck and a premium daily driver. New at Napleton Buick GMC in Crystal Lake, this crew cab arrives in Glacier White Tricoat — a pearlescent tri-coat white — over an Alpine Umber full-grain leather interior, with delivery miles only on the odometer.

The Max Trailering Package brings an 11,750-lb. GVWR and the Gooseneck/5th Wheel Prep Package, giving this truck a hitch platform ready to accept a gooseneck or 5th-wheel hitch straight from the factory.
The ProGrade Trailering System pairs with HD Surround Vision, a bed-view camera with two trailer camera provisions, Trailer Side Blind Zone Alert, and Trailer Tire Pressure Monitor Sensors — the full technology suite for confident pulling on the interstate or at the job site. The 2-speed active transfer case and X31 Off-Road Package add another dimension: 20-inch ultra-bright machined aluminum wheels wrapped in LT275/65R20 all-terrain tires mean unpaved roads and off-pavement worksites are equally at home.
A spray-on bedliner with GMC logo, LED cargo area lighting, and a 120-volt bed-mounted power outlet round out the work-ready equipment.
Inside, the Denali Ultimate trim delivers on comfort in every row. The front bucket seats are heated and ventilated; the driver's seat includes a Safety Alert function. Second-row outboard seats are heated as well.
A power sunroof opens the cabin, and the Signature Denali Ultimate Grille in Vader Chrome announces the trim level at a glance. The 13.4-inch diagonal premium GMC infotainment system features Google Built-In apps including navigation and voice assistance, wireless Apple CarPlay and Android Auto, and a Bose Premium Series 12-speaker audio system.
Wireless charging, a remote vehicle starter, power sliding rear window with defogger, front rain-sensing wipers, keyless open and push-button start, and deep-tinted glass are all included. Connectivity needs are covered by SiriusXM with 360L trial subscription, a mobile hotspot, and multiple USB charge and data ports.
Driver-assistance technology includes forward collision mitigation, pedestrian impact prevention, Ultrasonic Front and Rear Park Assist, Rear Cross Traffic Alert, and a rear camera. All-weather floor liners (first and second rows) are fitted from the factory.
