2020 Chevrolet Silverado 3500: What's New, Specs & Features
Last updated August 4, 2026
The 2020 Chevrolet Silverado 3500 HD is fully redesigned for the start of its fourth generation. The headline change is an all-new heavy-duty truck with a larger cab, stronger capability, and new gas and diesel powertrain combinations.
About the 2020 Chevrolet Silverado 3500
4th-generation Silverado HD, first year of the redesign.
Chevrolet positions the Silverado 3500 HD as a heavy-duty truck built first for towing, hauling, and jobsite use, but with more cabin space and technology than the old truck. The core appeal is broad configuration choice, very high tow ratings, strong gas or diesel powertrains, and towing-focused camera and trailer-management technology. Against rivals, Chevrolet leans heavily on its towing-tech story, the diesel/Allison pairing, and a lineup that runs from basic work trucks to the luxury-focused High Country.
The Work Truck is the job-focused version, with durable flooring, a 7-inch touchscreen, smartphone integration, and large trailering mirrors. LT adds everyday convenience, while LTZ brings leather, heated seats, LED lighting, and an 8-inch touchscreen. High Country is the luxury-focused model, with ventilated front seats, navigation, Bose audio, wireless charging, and its own front-end design.
What changed, by category
Powertrain
A new 6.6-liter gas V8 is standard across the lineup. The 6.6-liter Duramax diesel is paired with a new Allison 10-speed automatic, while the prior flexible-fuel powertrain is dropped.
Styling
The redesigned truck gets a new, larger heavy-duty body. Each trim has a more distinct look, from the Work Truck’s simple black grille treatment to the High Country’s unique front end and LED lighting.
Tech
The touchscreen becomes standard on LT and LTZ, and LTZ gains a standard heated steering wheel. The redesign also brings a broader set of towing-focused technology.
Structural
A new frame, larger cab, and expanded cab, bed, and chassis-cab configurations improve space and work flexibility. Towing and payload capability increase, and larger redesigned trailering mirrors become standard.
