Like their smaller, half-ton siblings in the Chevrolet truck lineup, the changes coming to the Bowtie’s 2021 heavy duty trucks are not groundbreaking. However, there are several smaller updates to know about and at least two other more interesting changes to look forward to in this model year including improved towing and a new Carhartt Special Edition of the trucks.

But let’s focus on the increased towing capacity first. Chevy says its engineers increased the HD lineup’s towing capacity by 500 pounds, paving the way for a max tow rating of up to 36,000—which Chevy says is the best available rating among Class 3 pickups.

If you want that 36,000 pounds of towing capacity though, you’ll need a very specific truck: a Silverado 3500 HD Work Truck powered by a 6.6-liter Duramax diesel in tandem with a 10-speed transmission, in a dually configuration with a regular cab and in two-wheel drive. Got that?

The full towing chart is below with the rest of the spec sheet on these trucks, but depending on the model, engine and cab, conventional towing ranges anywhere from 14,500 pounds to 20,000 pounds, while 5th wheel/gooseneck ranges from 16,120 to 36,000 pounds.

And in terms of engine/powertrain options, those are unchanged from 2020. You still have two engine options: the 6.6L gas V8 with 401 hp and 464 lb-ft of torque, or the 6.6L Duramax diesel with 445 hp and 910 lb-ft of torque. Available tranmissions are the 10-speed Allison or the 6-speed Hydra-Matic.

 

Carhartt Special Edition

The second thing to look forward to is the new Carhartt Special Edition.  This package will be available on both the 2500 and 3500. Chevy says production on this edition will start soon. We’ve got a full walkaround and all the details of this package in this video:

In addition to the Carhartt edition, Chevy will also be offering the following:

  • Midnight Edition

    Towing tech

    Circling back around a bit to towing, Chevy continues to push forward on tech and camera systems focused on making towing and trailering easier. Like last year, you’ll still be able to get 15 different camera views at whatever you’re pulling.  Here’s what they’re offering:

    Trailer Length Indicator: When changing lanes with the turn signal activated, a red overlay twice the length of the trailer is shown on the center console screen, which can help show when other vehicles are present.

    Jack-Knife Alert: Tracks the position of the trailer in relation to the vehicle and provides an alert if a potential jack-knife situation is imminent.

    Cargo Bed View Enhancement: Cargo Bed Zoom View and Bed Hitch Guidance are now available, which help to align and hook up a gooseneck/fifth-wheel trailer.

    Rear Trailer View Now Features Guidelines and Trailer-Angle Indicator: Enhanced to include assisting guidelines when backing a compatible trailer into place and a Trailer-Angle Indicator shows the relationship between the truck and trailer.

    Rear Side View Enhancement: Provides a split view, automatically biased based on the trailer’s angle, of the left and right sides of the truck and compatible trailer. This view was previously only available while driving forward and is now available in Reverse for better visibility when positioning a trailer.
