Key Features of the 2026 Chevrolet Silverado 2500 HD

6.6-Liter V-8 Gas and Duramax 6.6-Liter Turbo-Diesel V-8

Chevrolet’s heavy-duty engine lineup gives you two high-confidence choices. The standard 6.6-liter gasoline V-8 makes 401 hp and 464 lb-ft of torque, a proven setup for mixed-duty use like equipment trailers, utility bodies, and daily hauling. Step up to the available Duramax 6.6-liter turbo-diesel V-8, and you unlock 470 hp and a towering 975 lb-ft of torque, along with a diesel-rated max tow of up to 36,000 pounds when properly configured. Both engines are matched to an Allison 10-speed automatic transmission that optimizes gear selection under load, helping keep the engine in its sweet spot while managing temperatures and terrain. Whether you are towing a skid steer during the week or a fifth-wheel on the weekend, this powertrain strategy is engineered to feel unflustered.

Allison 10-speed Automatic Transmission

Transmission tuning matters when you are moving serious weight, and the Allison 10-speed automatic is a core reason the Silverado 2500 HD feels so composed. The wide ratio spread supports smooth takeoffs, controlled downshifts on grades, and quick response when you need to accelerate with a trailer. It pairs seamlessly with both the gas and Duramax engines, and its calibration helps manage engine braking and load transitions that can unsettle lesser gearboxes. The result is refined performance whether you are creeping around a job site, merging onto the highway, or navigating tight rural intersections with a long trailer in tow.

14-Camera Surround-View with Transparent Trailer

The Silverado 2500 HD’s camera suite brings clarity to otherwise stressful maneuvers. With up to 14 available camera views, including hitch guidance perspectives and a Transparent Trailer view, the system helps you line up, monitor, and maneuver with confidence. Transparent Trailer uses a clever composite of camera feeds to virtually “see through” a compatible trailer, improving situational awareness when merging or backing in tight spaces. Add in the way the system supports stored trailer profiles—making it easy to track maintenance and tailor settings—and you get a daily advantage that is especially valuable on busy job sites or crowded campgrounds.

13.4-Inch Google-based Infotainment with Apple CarPlay and Android Auto

Designed around usability, the Silverado 2500 HD’s infotainment system is intuitive and powerful. On LT, LTZ, Trail Boss, High Country, and ZR2, a 13.4-inch touchscreen anchors the dash, backed by helpful knobs, hard keys, and voice commands. The Google-based interface integrates maps, assistant, and the apps you rely on, while standard Apple CarPlay and Android Auto make smartphone connectivity seamless. Available wireless charging keeps your device topped up, and the system supports stored trailer profiles and app-based trailer functions for added convenience. It is a cabin built to work as hard as the chassis, keeping you connected without distractions or complexity.

Trail-Ready ZR2 and Z71 Off-Road Hardware

When your routes extend beyond the pavement, the Silverado 2500 HD has the hardware to keep you moving. The Z71 Off-Road package brings all-terrain tires, upgraded suspension, and underbody protection—smart upgrades for gravel roads and job sites. For even more capability, the ZR2 takes it further with a suspension tune that impressed editors on and off the trail, demonstrating control and composure across rutted, sandy, and rocky terrain. Pair either setup with four-wheel drive and the truck’s inherent chassis strength, and you have a heavy-duty platform that feels prepared for adverse weather, seasonal farm trails, and backcountry access roads that come with work and play.
