Back in November of last year, GM Authority exclusively reported that GM and Navistar were exploring jointly developing and producing a new Class 7 Truck, with a possible Chevrolet model becoming and addition to the Chevrolet Silverado Medium Duty line. While we have yet to hear further developments on that front, we now know that the current 2020 Silverado 6500HD Medium Duty truck will offer more capability than ever before.
The new capability comes in the form of an increased gross vehicle weight rating (GVWR) to a maximum of 23,500 pounds, up from the previous GVWR of 22,900 pounds maximum on the Class 6 Silverado. The gains come in the form of a new package for 6500HD models in 2WD that’s assigned RPO code DD7. This package provides a nice bump for the 2020 Silverado Medium Duty maximum GVWR, delivering big improvements when it comes to towing.
A similar option will be offered with 4WD models, but with a slightly lower 23,000-pound GVWR.
What’s more, 2020 Silverado Medium Duty models will also be offered with an optional 37,000-pound Gross Combined Weight Rating (GCWR) up-fit. That particular package is assigned RPO code R6Y.
The higher ratings are mostly made possible by the new Allison A2750HS six-speed transmission. What’s more, the new package also includes 225/70R19.5 H 130/128 L BW HWY Continental tires with a max axle load of 8,000 pounds in the front and 225/70R19.5 H 130/128 L BW HWY Continental tires with a max axle load 15,500 pounds in the rear.
As we exclusively covered back in May, the Silverado Medium Duty trucks will add a new 22.5-inch wheel option in the near future. That package has not yet been announced as of this writing.

The above table shows the GVWR breakout for the 2020 Silverado Medium Duty. The last two rows show the new packages that deliver increased GVWR.
To note, the 2020 Silverado Medium Duty truck was jointly developed by GM and Navistar. Production takes place at Navistar’s plant in Springfield, Ohio.
