Incorrect. Ram 3500 with the SRW and Cummins only comes with the 3.42 axle. Gas engines will allow you other ratios.
Once you go to the DRW, you can get 3.42, 3.73 or 4.10.
Literally the ONLY mechanical difference between the 2500 and 3500 SRW is the 500 lbs difference on the rear axle due to the leaf springs or air bags. The parts are all the same outside of the suspension.
