It might just be that GM only offers 3.73 gears where as you can get a 4.10 option from Ram and even a 4.30 option (I believe) from ford. Seems ford even used to offer 4.88's.
Also, maybe since they knew they were going to be coming out with the class 4 and up trucks real soon, they want to sell those for heavy work and not have them competing with the 3500 line.
thanks, that makes sense, no 4:10. that probably accounts for half of the difference. that is the type of factual answer i was looking for, not the numbers don’t matter or gm doesn’t want to brag. without a 4:10 they will not be able to tow as much. for example, a ram is rated about 21k with a 3:42, 26k with a 3:73, and 31k with a 4:10. changing those gears makes a big difference.
