Key Features of the 2026 Chevrolet Silverado 3500 HD

Duramax 6.6-liter Turbo-Diesel V-8

The available Duramax diesel 6.6-liter V-8 sets the tone for serious towing, delivering 470 horsepower and 975 lb-ft of torque. It is engineered to move heavy loads with ease, offering low-end grunt for initial launch and steady, predictable pull on the highway or across grade changes. Pair it with rear- or four-wheel drive and single- or dual-rear-wheel axles to fit your routine, and you will appreciate how seamlessly it partners with the Allison 10-speed automatic. If your schedule includes frequent fifth-wheel or gooseneck towing, the Duramax diesel is the muscle you want in your corner—built to maintain momentum, manage heat, and sustain performance under the longest, toughest hauls.

Allison 10-speed automatic

Both the gas and diesel engines pair with an Allison 10-speed automatic that is tuned for heavy-duty tasks. The spread of ratios helps keep the engine in its ideal power band, whether you are climbing at speed with a full trailer or inching into a tight jobsite with precision. With a transmission that is this smart, shifts feel calm and deliberate, towing feels stable, and downhill control becomes more predictable. On long days, this finesse helps reduce fatigue, especially when combined with the Silverado HD’s poised ride quality relative to its size and capability.

36,000-pound Max Towing with 14-camera Trailering Tech

When you configure correctly, the Silverado HD is rated to tow up to 36,000 pounds. Just as important as the rating is how easily the truck helps you manage that capability. The available 14-camera surround-view system offers perspectives designed for the realities of towing, including a transparent trailer view that virtually sees through the trailer for clearer awareness when merging, changing lanes, or easing into a parking space. Add in adaptive cruise control optimized for trailering to promote consistent spacing on the highway, and you have a confidence-inspiring combination of power and visibility that helps transform challenging towing into a routine you control.

Up to 7,442-pound Payload and Bed Utility

The strongest Silverado 3500HD with a regular cab and dual-rear-wheel axle can carry up to 7,442 pounds of payload. The heavy-duty bed and frame are built to support real-world loading, whether you are stacking materials, moving equipment, or setting up for a long tow day. Available bed features add meaningful convenience, including LED cargo lighting to keep work moving after dark and spray-in protection that stands up to daily wear. With smart storage and robust tie-down solutions, the truck is ready for whatever your checklist requires.

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

The technology in the cabin is just as purposeful as the capability under the hood. A 13.4-inch Google-based infotainment display is standard on key trims and includes Apple CarPlay and Android Auto. Physical knobs and buttons complement the touchscreen and voice commands, making it easier to interact with core functions while wearing gloves or focusing on traffic. Trailering support continues inside with the ability to store trailer profiles, monitor maintenance, and coordinate certain functions via a compatible smartphone app. Available wireless charging and a thoughtfully designed interior layout help the crew stay powered and organized throughout the day.
