2020 Chevrolet Silverado 2500: What's New, Specs & Features
Last updated August 4, 2026
The 2020 Chevrolet Silverado 2500 HD is a full redesign and the first year of its fourth generation. The biggest change is an all-new heavy-duty platform with a stronger chassis, a larger cab and bed, and a new standard 6.6-liter gas V8.
About the 2020 Chevrolet Silverado 2500
4th Silverado HD generation, first year of the redesign.
Chevrolet positions the Silverado 2500 HD as a heavy-duty pickup built to do serious towing and hauling without giving up everyday usability. The big selling points are work-ready strength, a wider range of trims from jobsite-basic to luxury-grade, and towing-focused hardware and camera technology that make big trailers easier to manage. Compared with rivals, Chevrolet leans especially hard on bed usefulness, towing confidence features, and giving buyers a broad range of personalities within one heavy-duty truck family.
The Work Truck remains the straightforward job-site model, while the new Custom adds body-color trim, 20-inch wheels, and a 7-inch touchscreen. LT adds everyday comfort, LTZ brings leather seating and LED lighting, and High Country tops the range with standard four-wheel drive, navigation, Bose audio, and wireless phone charging.
What changed, by category
Powertrain
A new 6.6-liter gas V8 becomes standard across the range, producing 401 horsepower and 464 lb-ft of torque. The Duramax diesel is paired with a new Allison 10-speed automatic. Flexible-fuel versions of the Work Truck, LT, LTZ, and High Country were dropped, while High Country added a gas version.
Styling
The redesign brings an all-new heavy-duty body and distinct grille treatments across the lineup. The new Custom trim adds a middle step between Work Truck and LT, with body-color exterior trim and 20-inch wheels.
Tech
Chevrolet adds more advanced towing technology, and trailering mirrors become standard across the Silverado HD lineup. LTZ also gains a standard heated steering wheel.
Structural
The 2020 truck moves to a stronger frame and chassis. Its crew cab and Durabed are larger, and the bed adds built-in side steps along with larger rear-bumper corner steps.
