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.

Very nice
I agree.
I would have hoped for a 26,000 lb GVWR with a dock height chassis (the 2wd trucks are lower) – but the specs they’ve shared in the article hints at the updated truck they are working on with the 22.5” wheels.
These trucks already appear to be well received after what seemed to be a slow roll out. I think Chevrolet’s biggest regret will be not having these trucks out sooner.
They could move even more trucks if they can get the gasoline model out already.
Dropping the mediums in 2010 cost GM a lot of commercial accounts. Now that they have gone this far, they should offer a truck that will compete with the F- 750. This also cost GM light truck sales also. I have yet to see one new 4500- 6500 Chey in NW Oregon.
So this mean it can tow 37,000 pounds cause I’m a little confused ?♂️
No it means that truck and trailer shall not exceed 37,000 lbs combined, in other words if truck weighs 12k, then you can tow additional 25k.
Very solid potential towing numbers.
Looking forward to seeing the new Class 7. Maybe they can get a tandem axle model for a Class 8 like they had with the Kodiak.
Finally starting to see these in the wild. It took a while to get these trucks out to the dealers and upfitters.
decalan is right Dubby.
These are about the only thing with “SIlverado” on the side that has been done right lately.
A pipeline/gas line contractor that has a an office in the park next to me bought a red one similar to the silver one pictured. It hauls tools but has a big water (maybe fuel) tank mounted between the boxes. He said he likes it so well that he’s ordered a flat bed and a flat bed dump to add to the fleet. But he said the biggest thing that tells how well received the truck is, his crew takes care of it! Even washing it!
When the 22.5″ rim/tire option debuts, we might see a 26,000 lbs. GVW on the 6500.
Please add a gas option
