The third-generation GMC Sierra 3500HD borrowed technology featured in the new 1500 model—launched the year prior—and mated it to a workhorse truck capable of serious heavy-duty hauling. The truck was designed to be highly configurable, offering a variety of cab options, two bed lengths, and three engine options. The truck received a full exterior and interior overhaul, further improving aerodynamics and ride characteristics like comfort and noise level. Vehicles featuring the 6.5- and 8-foot bed options included CornerStep bumpers as standard equipment, along with EZ Lift and Lower tailgates and an LED bed light. Inside the cabin, drivers gained standard access to features like MyLink infotainment, Bluetooth audio, USB ports, a premium Bose audio system, and OnStar navigation.
