Dealer notes
This 2026 GMC Sierra 2500HD AT4 is a new crew-cab diesel pickup at Napleton Chevrolet Buick GMC in Beaver Dam, WI, with delivery miles only. It arrives in Sterling Metallic — a cool, light metallic silver — over a Jet Black with Kalahari Accents interior, and it's built for the driver who wants diesel torque, genuine off-road hardware, a snow-plow and camper-ready electrical platform, and a quiet, well-equipped cab to come home to.
At a glance: 6.6L V8 diesel · 10-speed automatic · four-wheel drive · crew cab / standard bed · delivery miles only · Sterling Metallic exterior / Jet Black with Kalahari Accents interior

The AT4 Premium Plus Package adds a power sunroof, the Technology Package, and an off-road high-clearance step. Under that is the X31 Off-Road Package and skid plates from the Snow Plow Prep/Camper Package, which also includes a 220-amp alternator — the kind of electrical headroom that matters when you're running auxiliary equipment or setting up a camper.
The two-speed transfer case with AutoTrac and four-wheel drive round out the off-road foundation.
For trailering, the ProGrade Trailering System comes paired with a bed-view camera and two trailer camera provisions, HD Surround Vision, trailer side blind zone alert, and rear cross traffic alert. A spray-on bedliner with the GMC logo and a 120-volt bed-mounted power outlet keep the bed working between tows.
Inside, ventilated and heated front seats, heated second-row outboard seats, wireless charging, a Bose premium audio system, and a power sliding rear window make the cab comfortable on a long haul. The gloss black header grille and grille insert bars give the exterior the AT4's signature dark trim.
Front rain-sensing wipers, deep-tinted glass, keyless open and start with remote start, and the safety alert seat round out the daily-comfort story. Forward collision mitigation, pedestrian impact prevention, ultrasonic front and rear park assist, and wireless Apple CarPlay and Android Auto complete the driver-assistance and connectivity picture.
The AT4 Preferred Package adds a power sliding rear window, LED smoked amber roof marker lamps, and a universal home remote. The Preferred Equipment Group 4SB layers on front and rear premium floor liners with removable carpet inserts, rear wheelhouse liners, and steering wheel audio controls, among other appointments.
