The 2021 Chevrolet Silverado HD is getting upgraded - including a bump in max towing capacity.

The maximum towing capacity has jumped 500 pounds to up to 36,000 pounds. That's on the 3500 HD Work Truck with a regular-cab configuration, dual wheels at the rear, two-wheel drive, the 6.6-liter Duramax diesel and10-speed automatic, and the Max Tow package.

The same new tech available on the light-duty Silverado that assists with trailering is now available. It includes a trailer-length indicator that helps the driver determine if other cars are present, a jack-knife alert that is meant to alert drivers before they jack-knife their trailer, a camera that can zoom in on the cargo bed, a system that helps guide a trailer hitch into place, camera guidelines to help when reversing up to a trailer, and a split view of the sides of the trailer while backing up.

Four special editions (Carhartt, Midnight, Z71 Sport, and Z71 Chrome will be available. All four will be available in late 2020 - production on the 2021 model started last month.

Additionally, some optional equipment will now be standard or available on lower-grade trims than before, and there are two more exterior paint colors available.
