The 2026 GMC Sierra 2500HD AT4 brings serious off-road capability to the heavy-duty truck segment with an off-road suspension package featuring twin-tube Rancho shocks, skid plates, and 20-inch gloss-black aluminum wheels wrapped in available BFGoodrich all-terrain tires. All this comes with refined touches like a Jet Black interior with Kalahari accents and heated, ventilated perforated leather seating. A sunroof allows you to take it all in. Beneath the hood, this AT4 runs with the proven 6.6L Duramax Turbo-Diesel V8 paired with a 10-speed Allison automatic transmission, delivering ample torque and impressive towing capability. This model also comes with a gooseneck / 5th wheel prep package, universal vehicle module and upfitter switch kit.
