2500 Chevy Duramax vs 2500 Ram Cummins on the Ike Gauntlet
Good to see some Ike Gauntlet pulls again and no surprise the Ram performed better than the Chevy in braking performance and fuel economy. Link

I had thought that Ram and GM use the same rear axle.
I thought so too, 11.5" AAM.
They do...or did anyways. I can't speak to the last couple years, but Ram does offer a larger axle in their dooleys and maybe 3500 srws. 11.8 ring gear, maybe a 12" model. And Ram went to a different/larger bolt pattern on the dooleys...
Now there's at least 4 different bolt patterns out there for current model 8 lug light duty trucks.
I don't follow it real close but I've not heard of a 12". I thought the 11.8" version was just on the HO models.
GM dually 2020 and up has a 12" ring gear
