Sierra 2500HD Duramax 4x4 ? Heavy-Duty Torque, Quiet Luxury, Zero Apologies This is the kind of truck that makes ?half-ton problems? disappear. Big-body Sierra 2500HD attitude, Duramax diesel punch, and that confident 4x4 stance that looks right rolling through Grand Rapids, sliding down I-94 toward Jackson, or chewing up backroads outside Angola like it?s a casual Tuesday. At the center of it all: a 6.6L Duramax V8 diesel paired to the Allison 6-speed automatic. Translation: deep pulling power, calm highway manners, and the kind of controlled strength that feels built for real work, not parking-lot cosplay. Add Z71 Off-Road, two-speed electronic transfer case, hill descent control, and off-road skid plate protection, and you?ve got capability that holds up when the weather turns ugly in Hillsdale County, the road gets rough in Defiance County, or the route gets unpredictable out in Allen County. The ?get stuff done? side is fully dialed: trailering package with integrated trailer brake controller, exhaust brake, heavy-duty cooling for the engine and transmission, plus the smart practical touches like a spray-on bedliner, movable cargo tie-downs, and a power sliding rear window. It?s built to pull, haul, and handle real-life truck jobs without acting dramatic about it. Then it hits you with comfort like it didn?t just show up to work: leather interior, heated front seats, heated steering wheel, power adjustable pedals, memory driver settings, and a cabin that feels more ?premium command center? than ?work truck.? Tech stays sharp with the up-level infotainment system with embedded navigation, rearview camera, front/rear parking assist, Bluetooth, and a premium performance audio system. You?ve even got wireless device charging and a 110V outlet, because your life has batteries now. Outside, it brings the presence: Iridium Metallic paint, 20? aluminum wheels, HID headlamps, front fog lamps, privacy glass, and chrome assist steps that make climbing in feel like stepping up to business. Because Everything We Do Is Driven By You. #GMC #Sierra2500HD #Duramax #DieselTruck #AllisonTransmission #4x4 #Z71 #HeavyDutyTruck #TraileringPackage #TrailerBrakeController #ExhaustBrake #HillDescentControl #SkidPlates #SprayInBedliner #Navigation #BackupCamera #ParkingAssist #RemoteStart #HeatedSeats #HeatedSteeringWheel #WirelessCharging #PremiumAudio #IridiumMetallic #TruckLife #WorkReady #TowReady #MichiganTrucks #OhioTrucks #IndianaTrucks #GrandRapidsMI #JacksonMI #HillsdaleMI #Hillsd
