I'm seeing all over the web and YouTube about the 35,500 lb towing capacity on the new 2020s. But I'm having a hard time finding out if this is GCWR or is this flat out hooking up 35,500lbs to the truck and towing it? Im Trying to compare to the Ram towing charts. On a Ram 5500 it shows 35,220 under "max towing" thats on the heaviest model.. Most show 34k. Does this really mean GMs 3500 has a higher towing rating than a Ram 5500!! Can anyone clear this up for me?

A 2WD, RC dually Duramax will tow 35,500 pounds. All dually trucks, no matter the configuration or trim will tow over 30,000 pounds.

I saw one article quote chevy that the actual towing capacity was 23500. Who knows? Like you said, 35000 is probably gcwr.

Regular cab dually 2wd diesel has a gcw of 43,500. The rest of diesel duallys have gcw of 40,000. Ford is at 40,000 with their f350 dually and Ram is at 43,000 with their diesel duallys.

I'm just trying to compare apples to apples, its not real clear. Ram 3500 trucks are showings 25k tow ratings, so GM is 10k more towing? GMs numbers are more comparable to a 5500!!

Ram can go to 35,100 with pickup and 35,220 with cab chassis.

What is really cool is that GM is getting these tow ratings with a 3.42 rear axle gear ratio, when the others are going much lower (higher numerically) gear ratio.

But I bet it won’t see 10th gear very much at those weights. Or It could be the the gearing out of the transmission is much different.

Exactly what it is.
Final drives will be different when comparing a 4sp vs a 10 sp.
With low first gear ratios a 4.10/4.56 is not needed anymore.
