Key Features of the 2026 Chevrolet Silverado 3500 HD

6.6L Duramax Turbo-Diesel V8

The available 6.6-liter Duramax turbo-diesel V-8 is the heart of the Silverado HD’s max rating. With 470 horsepower and a towering 975 lb-ft of torque, this engine turns steep grades and heavy trailers into manageable tasks. Its diesel torque curve delivers muscle down low, right where you need it to get moving, to stay steady on uneven terrain, and to pass decisively while towing. Properly configured, the diesel-powered Silverado HD can tow up to 36,000 pounds, and the dually setup amplifies stability under big fifth-wheel and gooseneck loads. Strength is only part of the story—the Duramax is refined and remarkably composed for such an engine, contributing to road manners that encourage long days and long distances.

6.6L Gas V8

The standard 6.6-liter gas V-8 produces 401 horsepower and 464 lb-ft of torque, a stout combination for owners who need reliable capability and predictable maintenance requirements. Matched to the Allison 10-speed, the gas engine feels responsive and steady whether you are towing equipment between job sites or hauling materials through rolling county roads. For many buyers who split their time between moderate trailering and daily driving, the gas V-8 hits a value sweet spot without compromising the confidence you expect from a one-ton truck.

Allison 10-Speed Automatic Transmission

Every Silverado HD powertrain benefits from the Allison 10-speed automatic. This transmission is tuned for heavy-duty work, spacing ratios to keep the engine in its ideal band and delivering smooth, deliberate shifts under load. The result is stronger control on climbs, sure-footed response when you ask for more throttle, and relaxed rpm at highway speeds. With rear- or four-wheel drive and available single or dual rear wheels, the Allison 10-speed complements your chosen configuration with refined drivability and durability you can feel, tow after tow.

14-Camera Trailering System with Transparent View

Trailering confidence is a Silverado HD hallmark, and the available 14-camera surround-view system anchors that advantage. Multiple views help you align a hitch, check cargo, and monitor traffic around your rig. A standout capability is its transparent mode, which can virtually let you see through a compatible trailer to view what’s directly behind you. That’s a major aid when changing lanes on the highway, backing into tight spots at the jobsite, or navigating busy lots. Add in the ability to store unique trailer profiles, monitor trailer maintenance, and interact through a smartphone app, and the truck becomes a comprehensive trailering partner—not just a tow vehicle.

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

Usability matters when you spend hours in the cab. The Silverado HD’s Google-based infotainment interface is thoughtfully laid out, with physical volume and tuning knobs for quick adjustments and voice commands to keep your focus forward. A larger 13.4-inch touchscreen is standard on LT, LTZ, Trail Boss, High Country, and ZR2 models, pairing nicely with standard Apple CarPlay and Android Auto. On select trims, an integrated wireless smartphone charging pad reduces cable clutter. Surrounding the tech is a cabin designed for productivity and comfort: available heated and ventilated front seats, heated rear seats, a heated steering wheel, ample storage including an oversized center console bin, and additional under-seat or seatback storage on certain models. For 2026, you can also dress the exterior in Polar White Tricoat and choose available Bright Finish 20-inch aluminum wheels for a crisp, modern look.
