2021 Chevrolet Silverado HD adds more towing capacity, tech and special editions

The 2021 Chevrolet Silverado HD can tow even heavier loads than last year! Shocking, we know. GM has upped its maximum towing capacity from 35,500 pounds to 36,000 pounds in its most capable variant (which happens to be the 3500 HD Work Truck with a Regular Cab, rear-wheel drive, dual rear wheels, 6.6-liter Duramax diesel and Max Tow Package).
