Key Features of the 2026 Chevrolet Silverado 3500 HD

Duramax 6.6L Turbo-Diesel V8 with Allison 10-Speed

The heart of the most capable Silverado 3500 HD configurations is the available 6.6-liter Duramax turbo-diesel V-8, rated at 470 horsepower and 975 lb-ft of torque. It is paired with an Allison 10-speed automatic that spreads power evenly and keeps the engine in its sweet spot, both on grades and in stop-and-go crawling with a heavy trailer. This powertrain underpins the truck’s maximum 36,000-pound towing capability when properly equipped, and it is designed for the repetitive strain of commercial work. Diesel-friendly features like an exhaust brake help you maintain speed on long descents while reducing brake wear, and integrated trailer brake controls deliver precise modulation. Whether you choose rear-wheel drive or four-wheel drive and single or dual rear wheels, this drivetrain has the muscle and control to manage high GCWR demands day after day.

6.6L Gas V8 Power with 10-Speed Automatic

The standard 6.6-liter gasoline V-8 provides 401 horsepower and 464 lb-ft of torque, also mated to the Allison 10-speed automatic. This pairing is smooth and predictable, with gearing optimized to keep you in the meat of the power band under load or while merging. The gas engine can tow up to 17,400 pounds when properly equipped, and it remains an excellent choice for mixed-use workloads, plowing, or fleets that prefer gasoline fueling. The proven 10-speed’s close ratios help with throttle response and grade performance, while the heavy-duty cooling and charging systems are engineered to withstand the thermal demands of tough use and long idling periods common in jobsite environments.

14-Camera Trailer System with Transparent Trailer View

Trailering is simpler when you can see more. The available 14-camera system provides vantage points around the truck and trailer that were previously impossible, including Transparent Trailer View, which virtually lets you see through a compatible trailer to what’s behind you. Hitch Guidance overlays help you back precisely up to the coupler, and additional views simplify lane changes, intersection turns, and tight parking maneuvers. Combine those visuals with the ability to store custom trailer profiles and track maintenance, and you have a work-ready system that streamlines your pre-trip checks and helps prevent surprises on the road. It is all about reducing guesswork and delivering confidence when inches matter.

13.4-Inch Google Built-In Infotainment

On LT and above, the Silverado HD’s cabin centers on a 13.4-inch touchscreen with Google built-in, standard Apple CarPlay and Android Auto, and voice commands that make it easy to manage navigation, calls, and apps while keeping your eyes up. Physical knobs and key buttons remain for volume and tuning, so you get tactile control even with gloves. Available wireless smartphone charging keeps cords out of your way, while USB ports and power outlets support tools and devices. Beyond the screen, you can equip the cabin with heated and ventilated front seats, heated rear seats, a heated steering wheel, and a head-up display to project key data into your line of sight. It is a functional workspace that is comfortable for long hauls and organized for busy days.

Heavy-Duty Hardware and What’s New

Every Silverado 3500 HD rests on a stout frame and suspension designed for demanding payloads, with options for single or dual rear wheels, regular or crew cab layouts, and short or long beds. Factory gooseneck/5th-wheel prep makes it easier to set up for serious towing, and integrated bed lighting and available spray-in bedliner add durability and utility. For 2026, Chevrolet adds Polar White Tricoat to the color palette and introduces Bright Finish 20-inch aluminum wheels in place of prior polished 20-inch units. Available adaptive cruise control tuned for trailering, blind-spot monitoring, rear cross-traffic alert, and forward-collision warning with automated emergency braking help you navigate busy highways with a loaded trailer, while robust interior storage solutions keep daily gear secured and accessible.
