This 2025 GMC Sierra 2500HD Denali 4WD is powered by the 6.6L Duramax turbo-diesel V8 paired with a 10-speed Allison automatic transmission. Finished in Summit White with a Jet Black perforated leather-appointed interior, this premium heavy-duty pickup features the Denali Reserve Package, Technology Package, power sunroof, body-color wheel arch moldings, and exceptionally low mileage.
The 6.6L Duramax delivers an impressive 470 horsepower and 975 lb-ft of torque, providing tremendous pulling power for campers, equipment trailers, and demanding workloads. Combined with four-wheel drive and the Allison 10-speed transmission, this Sierra offers serious heavy-duty capability with the comfort and refinement of a Denali.
The Denali Reserve Package adds to this truck's premium appeal, while the body-color wheel arch moldings give it a cleaner, more refined appearance. The signature chrome Denali grille, polished exhaust tip, and Summit White exterior complete its upscale styling.
Inside, the Jet Black leather-appointed interior offers heated and ventilated front seats, heated rear outboard seats, a spacious center console, and premium materials throughout. The power sunroof adds an open feel to the cabin, while the Bose Premium 7-speaker sound system delivers excellent audio quality.
The Technology Package brings some of GMC's most desirable features, including a massive 15-inch multicolor Head-Up Display, HD Surround Vision, Rear Camera Mirror, and Bed View Camera. These features provide excellent visibility and convenience when driving, parking, or maneuvering with a trailer.
Advanced trailering technology includes trailer camera provisions, trailer viewing software, and Trailer Side Blind Zone Alert. The Bed View Camera makes monitoring cargo and trailer connections easier, while the available camera views are especially useful when handling larger trailers.
The X31 Off-Road Package adds additional capability for rough terrain, gravel roads, and challenging conditions. A two-speed transfer case and Hill Descent Control provide added confidence when traveling off pavement.
Additional equipment includes wireless charging, wireless smartphone connectivity, remote start, rain-sensing wipers, Rear Cross Traffic Alert, front and rear parking sensors, a Safety Alert Seat, power-sliding rear window, factory spray-on bedliner, LED cargo lighting, and 120-volt power outlets in the bed and cabin.
Mileage is another major advantage, with the odometer reading 7,684 miles below the market average.
