2025 GMC Sierra 2500HD Denali 4x4

THIS… is a 2025 GMC Sierra 2500HD Denali 4x4, finished in Downpour Metallic with an Alpine Umber interior. According to the window sticker provided in the gallery, notable factory equipment includes the Gooseneck/5th Wheel Prep Package, a MultiPro tailgate with audio system by KICKER, heated and ventilated front seats, and more as detailed below. The seller reports no notable modifications. GMC launched the current-generation Sierra for 2019. The truck was again related to the Chevrolet Silverado under the sheet metal, but designers went to great lengths to differentiate the two models; they notably gave the front end a new look. GMC also offered some features that were not available to Chevrolet buyers at launch, like the clever MultiPro tailgate. Power comes from a Duramax 6.6-liter turbodiesel V8 engine, rated at 470 horsepower and 975 lb-ft of torque. Output is sent to the rear or all four wheels via an Allison 10-speed automatic transmission.
