Dealer notes
This 2026 GMC Sierra 2500HD Denali Ultimate is a new crew cab 4WD pickup — with delivery miles only — at Napleton Chevrolet Buick GMC in Beaver Dam, WI. It arrives in Onyx Black over an Alpine Umber full grain leather interior, and its build centers on one idea: flagship comfort that holds up anywhere Wisconsin takes you, from a snow-covered job site to a long stretch of interstate with a trailer behind.

The Preferred Equipment Group 5SB is the centerpiece of this build, and it starts at the front with the Signature Denali Ultimate Grille in Vader Chrome — the detail that sets this truck apart on the lot and in the rearview mirror. Inside, driver and front passenger seats are heated and ventilated in full grain leather, second-row outboard seats are heated, and a power sunroof opens the cabin up.
A Bose Premium Series 12-speaker system fills that cabin, paired with the 13.4-inch diagonal GMC Infotainment System with Google Built-In apps for navigation and voice assistance, plus wireless Apple CarPlay and Android Auto, wireless charging, and a mobile hotspot. A safety alert seat and front rain-sensing wipers handle the details so you don't have to.
The same package equips this truck for serious work. The ProGrade Trailering System brings trailer tire pressure monitor sensors, trailer cam provisions and trailer viewing software, a bed-view camera with two trailer camera provisions, trailer side blind zone alert, and HD Surround Vision .
A 120-volt bed-mounted power outlet and LED cargo area lighting make the bed a worksite. The X31 Off-Road Package — included in the 5SB — pairs with 275/65R20 all-terrain tires on 20-inch ultra-bright machined aluminum wheels.
The Snow Plow Prep/Camper Package adds a 220-amp alternator and skid plates for Wisconsin winters and heavy-duty use. A spray-on bedliner with GMC logo, rear wheelhouse liners, and black front and rear molded splash guards protect the truck from the work it was built for.
Keyless open and start, remote vehicle starter system, and a power sliding rear window with defogger round out a build that was thought through to the last detail. All-weather floor liners for the first and second rows come fitted from the factory.
