I find it hard to come to a conclusion of a winner. The Ram did very well considering the 2500 has a de-rated 370 hp. Only the 3500 Ram truck is available With the high output Cummins and Aisin transmission (still a 6 speed).

The 2020 and up Chevy/GM's only come with a 3:43 rear-end, and that is both for the 2500 & 3500's. The gas motor comes with a 3:73.
