This engine is paired with a 6-speed automatic transmission, and you can choose between rear-wheel or all-wheel drive. The engine has a maximum towing capacity of 18,500 pounds, enough to easily haul a fifth-wheel trailer, a horse trailer, or a boat. The engine can also handle payloads of up to 3,979 pounds, so you can carry heavy equipment, materials, or tools in the truck bed. Thanks to its advanced off-road package, the 2023 GMC Sierra 2500HD is built to handle rough terrain. The package includes skid plates, heavy-duty shock absorbers, and an upgraded suspension system. Depending on the terrain, the truck also has a 2-speed transfer case that allows you to shift between high and low-range four-wheel drive. The truck also has an optional hill descent control system that helps you maintain a steady speed when driving down steep hills. Contact us at Dearth GMC today.
