Key Features of the 2026 Chevrolet Silverado 2500 HD

6.6L Gas V8 or Available Duramax 6.6L Turbo-Diesel V8 with Allison 10-Speed

Under the hood, the Silverado 2500 HD offers two heavy-hitting choices tailored to how you work. The standard 6.6L gas V8 is rated at 401 horsepower and 464 lb-ft of torque, pairing naturally aspirated response with the Allison 10-speed automatic’s smart gearing to keep power on tap at low speeds and steady-state highway cruising. For maximum torque and top-tier towing confidence, the available Duramax 6.6L Turbo-Diesel V8 delivers 470 horsepower and 975 lb-ft of torque. It’s the combination to choose if you regularly pull long grades, haul heavy equipment, or want ultimate reserve power in headwinds and heat. Both engines are offered with rear- or four-wheel drive and can be configured with single or dual rear wheels. Together with a robust frame and cooling systems, the HD powertrain lineup is engineered for sustained workloads, predictable throttle modulation when backing trailers, and reassuring engine braking on descents.

Towing and Payload Capability

Capability is the benchmark of any heavy-duty truck, and the Silverado 2500 HD delivers. Properly equipped, the diesel-powered models can tow up to 36,000 pounds, while gas-powered models offer substantial tow ratings that suit contractors, ranchers, and weekend enthusiasts alike. Payload capacity varies by configuration, and the line is designed to balance axle ratings, wheelbase, cab choice, and bed lengths for the right mix of people and payload. The engineering focus is evident in hitch hardware, available gooseneck/5th-wheel prep, integrated trailer brake controller, and driveline components designed for repeatable performance. The Silverado 2500 HD team also optimized ride quality, so even when you are not working at max capacity, the truck remains composed and comfortable over long distances and across broken pavement.

14-View Camera System with Transparent Trailer View

Visibility is confidence, and the Silverado 2500 HD’s available 14-view camera system is designed around the realities of trailering. Multiple exterior camera angles make it easier to line up to a hitch, monitor cargo areas, and keep tabs on the traffic around you. Transparent Trailer View, one of the most appreciated tools in the system, virtually lets you see through a compatible trailer for a clearer look behind you when merging, changing lanes, or navigating tight parking lots. When attached to longer trailers, the combination of side and rear angles reduces guesswork and helps you maintain awareness. Whether you are guiding a gooseneck into a jobsite or backing a boat down a ramp, the camera suite is a practical advantage that reduces stress and saves time.

Google built-in with 13.4-inch Diagonal Touchscreen

Technology in the 2026 Silverado 2500 HD is designed to be useful, not distracting. Trims such as LT, LTZ, Trail Boss, High Country, and ZR2 include a 13.4-inch diagonal touchscreen that runs Google built-in, integrating Google Assistant, Google Maps, and a growing ecosystem of in-vehicle apps. Standard Apple CarPlay and Android Auto let you bring your smartphone’s interface onboard, while physical knobs and buttons for core functions make adjustments easy with gloves on. For frequent towers, the infotainment platform supports trailer profiles, so you can record mileage, track maintenance, and tailor settings for different loads. Available wireless smartphone charging keeps devices powered without cables, and the interface supports voice commands for hands-on-the-wheel operation. The result is a cabin that is as connected as your office, but built for the grit of real work.

ZR2 and ZR2 Bison Capability

When your schedule takes you past the pavement, the Silverado 2500 HD ZR2 and ZR2 Bison are ready. These specialized models add all-terrain tires, upgraded suspension tuning, and underbody protection that stand up to rocky two-tracks and unpaved access roads. Skid plates, unique dampers, and chassis tuning enhance articulation and stability without sacrificing the controlled ride the HD is known for. The ZR2 Bison layers on additional protection and trail-focused details for drivers who regularly thread long-wheelbase trucks through challenging terrain. Tested on demanding desert trails, these trucks combine stout hardware with the same trailering features found across the lineup, so you can reach remote job sites, hunting camps, and campsites with confidence—loaded or unloaded.
