It's been known for years, assuming using the same axle, that taller gears due to bigger teeth are stronger than lower ones. Then putting in a say 12.5" diff vs an 11.5" did gears, those gears generally speaking weigh more, more drive train loss, fuel used etc.
With that, a 4.10 12.5 will be stronger than an 11.5" rp. I'm sure their are other positives to the larger gears....
At the same time, are the front diffs getting larger to meet power going to them in 4wd?
Yeah I'm asking questions along with some facts that I know. I also know there is no real right or wrong regarding this issue.
I'll leave it at that.

I know the front diffs got larger at some point to handle more load capacity, but not sure about to handle more torque. Having said that the Super Duty's got a larger front diff (Dana super 60) in 05 and Ram got a larger diff in '13 and believe they haven't changed since.
