Which ratio should I go with? The dealer says that the 373's are standard and recommended for up to a 36" tire. I am thinking the 410's would be better. It will be on an automatic FWIW..

3.73 on a rubi? I was always under the impression they came standard with 4.10s

Get the 4.10 unless you only drive highway flat surfaces.

My '12 has 4.10's. It seems perfect with 35s. If you aren't gonna get bigger tires I think 3.73s would get better fuel mileage, I guess you have to figure out your future plans and go from there.

The 2012's starting coming standard with the 3.73 and you had to upgrade to the 4.10. I would recommend the 4.10 unless you plan on upgrading right off the bat.

Gonna go with 35's. Plus I already have front and rear bumpers and a 125 pound Warn power plant. I am thinking 410's. I was just looking for confirmation on my decision. Or for someone to tell me that I was a DA and the 410's weren't necessary.

I think you're headed in the right direction. I'm very happy with my choice of 4.10s.

Get the 4.10's.

The 2012's come standard with the 373's unless you get the max tow package that upgrades to 410's. I had the dealers search a 500 mile radius when I was buying, and couldn't find exactly what I wanted. I ended up with 321's on my sahara and plan to upgrade.

What mileage are you guys getting with the 373's and 35's versus 410's and 35's on a 2012 with an auto?

With 4.10s, 35s and an auto I get mid 15 mpgs combined driving. I'm pretty happy with that. I only have 1300 miles on mine, it may get even better.
