GMC Sierra 2500 HD Mechanical specs
Underneath, the Sierra 2500 HD is engineered for confident control whether you’re towing heavy, picking through worksites, or tackling rutted access roads. The foundation is a strong frame paired with a standard 10-speed automatic transmission that keeps the gas or available Duramax® diesel in an ideal power band. The Traction Select System with Tow/Haul mode helps tailor throttle and shift response to load and road, and the integrated Trailer Brake Controller and Trailering Mirrors build in essential stability and visibility. Available off-road hardware varies by trim, with AT4 adding an Off-Road Suspension Package that includes twin-tube Rancho® shocks and skid plates, while AT4X takes it further with Multimatic® DSSV dampers, a rear electronic-locking differential, and upgraded skid protection. Up to 14 available camera views, including Transparent Trailer View, stitched by HD Surround Vision, bring real-time angles to your screen that can make positioning and backing smoother in tight yards. At Jones GMC, we help you align hitches, tire packages, and bed setups with real-world demands, from weekend fifth-wheel trips to weekday equipment hauling, so your Sierra 2500 HD is set up right the first time.
