Thanks guys, great feedback!

2.72, 3.8, 10.34 are so close to your first choices I doubt you could tell the difference.
Good point Doug. I been over thinking it.

So... revisiting this, really thinking on the 4 speed meow.

2.72, 2.00, 5.44
Thinking the 2.00 would be good cruising up the trails in 2LO, 2.72 would be good just random crawling and 5.44 for the rough stuff.

Any opinions on this set-up good or bad?

i think i'd go a little lower on the 2.72. a 3.8 would be a good ratio or even a 3.0

Agreed.
My dana 300 is 2.62:1. With my manual trans having a 6.7:1 first, it works well, but if I had anything higher (like an auto) I'd want a lower tcase. I think 2.72 would leave you wanting more, and i would lean toward the 3.8 if I had a choice (FWIW, I will be going 4:1 in my case eventually)

Ah. So just use the reduction OR the box and not worry about using them both?

I have not got to wheel mine atlas 4 yet but after speaking with AA for a long period of time i went with 3.8. Gives you the most options of any gear combo for the 4.  More options available to you. I have always heard 4.0 was great so 3.8 got me damn close and if needed i can go to 10.3.  AA said that the 4.3 and 11.7 would probably be to low to use the 11.7 at all, if ever.  With all that said i will be running a 6.0 ls, 4l70E, and 3.73 gears on 35's. Trying to have the best of both worlds street and trail.

For  what we do, extremely low gearing is of most use in steep downhills while staying off the brakes.  Of course, if you want to crawl Boatramp and 1 inch/minute with stickies or go out to Moab frequently then low gearing is great.

Crawl ratio that includes transmission and axle gearing can help decide transfer case gearing.  If 11.7 is too low you can always shift into 2nd.

Accidentally ending up too low is just a great excuse for larger tires. Gotta find the positives in everything That being said....my vote would be for the 3.8 for the options. Gotta make sure you have a gear for wheel speed around here.

Thanks everyone. This information helped a lot!

Still going back and forth with the 4 and the 2.
After this weekend, I may end up with just the 2. Still undecided though.
