So with the new info I used 6.5 crawler first, 2.72 transfer case F-150, and a 4.7 final gear comes in at 83.1 crawl ratio in my calculator. Right in the Rubicon range. (y)(y)
I BET there will be a lower transfer case optional for higher trims

Well in that case, since you brought it up, if I use the Rubicon's 4.1 case, which is also the same as the Atlas commonly use in the off road world, ……………… it's a staggering 125.3 !!!!!!

........so at the least the base Bronco has a crawl ratio on par with the Rubi's (y) (y)

at that point I could set it to holdmax RPM and still walk beside it....

Going to try to revive this since most of the talk was before the specs came out I’m considering a black diamond with the seven speed and 2.3. It’s gears on that are 4.46, looks like badlands with 33” tires is 4.7. If I wanted to mount 33” is the 4.46 enough? One would think so? Might mess up the creeper gearing?

7MT, 4.46 rear, and Advance 4X4 transfer case is a crawl ratio of 89.1

7MT, 4.7 rear and Advance 4X4 transfer case is a crawl ratio of 94.75

now that we know the numbers to put in my calculator.
