This 2015 GMC Sierra 2500HD Denail 4x4 crew cab is finished in Summit White over black leather. Originally a Z71 Off-Road truck, much of the suspension has been replaced with modified components. Options include the Duramax Plus package and Driver Alert Package, and the truck shows just under 7,900 miles at the time of listing. This modified 2500HD Denali is being sold on consignment by Exotic Car Trader with a clean title and a clean Carfax.


This 2015 GMC Sierra 2500HD sports an extensive list of exterior modifications, from AMP Research power side steps and Bushwacker fender flares to a Cognito leveling kit and lift with Fox shocks and custom white powdercoating. 24" Fuel wheels and 38" Nitto tires ride beneath, and Rigid Industries LED lights adorn the color-matched grille and front bumper. Tinted tail lights, custom badges, a Line-X spray-in bedliner, and an 8" chrome exhaust tip round out the exterior modifications. The Summit White paint is noted to be in excellent condition. The cabin features an 8” Bluetooth infotainment system and upgraded luxury materials as part of the Denali trim level. This 2500HD Denali is optioned with heated and cooled front seats trimmed in perforated leather. Another option is the Driver Assist Package which adds Lane Departure Warning, Forward Collision Alert, Front and Rear Park Assist, and a vibrating Safety Alert Seat on the driver’s side. A myriad of USB ports, cigarette ports, and a household three-prong outlet are found below the center controls. The digital odometer displays 7,886 miles at the time of documentation.


Under the hood lies a 6.6-liter Duramax diesel V8 producing 397 horsepower and 765 lb-ft of torque channeled to all four wheels through an Allison 6-speed automatic transmission. Fittingly for such a high amount of torque, this 2500HD has been fitted with Nathan AirChime K5 genuine locomotive horns and a VIAIR 5 Gallon 4 Port 150 PSI air tank. An AFE cold air intake and a custom tune round out the truck’s modifications.
