      Notes from the dealer

      2026 GMC SIERRA 2500HD DENALI ULTIMATE 4WD 6.6L DURAMAX LIFTED FOX SHOCKS BLACK 22s PAINT MATCHED ONYX BLACK LANCASTER PA

      This 2026 GMC Sierra 2500HD Denali Ultimate 4WD is powered by the 6.6L Duramax V8 turbodiesel paired with a 10-speed automatic transmission. Finished in Onyx Black, this isn't your typical Denali Ultimate. It's lifted, riding on FOX shocks and black 22-inch wheels, with a paint-matched exterior that gives GMC's flagship HD truck a completely different attitude.

      Start with the stance because that's impossible to miss.

      The lift and FOX shocks give this Sierra the height and aggressive look a factory truck simply doesn't have. Add the black 22s and paint-matched treatment, and the whole truck comes together instead of looking like somebody randomly bolted parts onto an expensive diesel.

      Underneath all of that is the 6.6L Duramax, producing 470 horsepower and 975 lb-ft of torque. Paired with the 10-speed automatic, it delivers the low-end muscle you want for heavy trailers, equipment, campers, or simply moving a truck this size without feeling strained.

      This one is ready for serious towing too. The factory Gooseneck/5th Wheel Prep Package is already there, along with a Bed View Camera, trailer camera provisions and viewing software, Trailer Side Blind Zone Alert, trailer tire-pressure monitoring, and HD Surround Vision.

      The X31 Off-Road Package adds factory off-road suspension and Hill Descent Control, complementing the upgraded stance and FOX setup when you're heading beyond clean pavement.

      Then you open the door and the personality changes completely.

      The Denali Ultimate cabin is finished in Alpine Umber leather with heated and ventilated front seats, heated rear seats, a 15-inch Head-Up Display, 12-speaker Bose Premium Series audio, Rear Camera Mirror, wireless charging, and a power sunroof.

      That's what makes this truck so good. Outside, it looks like a custom-built lifted Duramax. Inside, it's still the top-shelf Denali Ultimate you can comfortably spend hours driving.

      You also get a factory spray-on bedliner, LED cargo lighting, power-sliding rear window, 120-volt outlets in both the cab and bed, front and rear park assist, and remote start. It's loaded, but none of the luxury gets in the way of actually using the truck.

      If you're searching for a lifted 2026 GMC Sierra 2500HD Denali Ultimate Duramax near Lancaster, finding another one configured like this won't be easy. Onyx Black, paint matched, FOX shocks, black 22s, Duramax power, 5th-wheel prep, X31, sunroof, and Alpine Umber leather make this one seriously different.
