Thanks for the link, s**t just keeps getting more expensive.
Have you ever driven anything with a 10:1 low range? Even with the manual that would be silly. With the automatic it wouldn’t even be useful. Yes I rock crawl. 4:1 is perfect for the manual, borderline too low for the automatic.My dear friends, the wishes of both of us are not the same
You are looking to travel the trails
I'm looking to crawl and climb rocks
Therefore transfer ratios in rocks are completely different from travel on trails.
See an example of what is available today for JK.
Ratio's of the Atlas 4Speed are:
1.5:1, 2.72:1, & 4.08:1 Recommended for all applications
2.0:1, 2.72:1 & 5.44:1 Recommended for all applications
2.72, 3.0:1 & 8.16:1 Recommended for all applications
2.72:1, 3.8:1 & 10.34:1 with this low gear ratio, high horsepower engines are not recommended
2.72:1, 4.3:1 & 11.70:1 with this low gear ratio, high horsepower engines are not recommended
There were several obstacles where the 4 speed atlas in my JK in compound low was an advantage. Having an engine like the 3.6 with a manual was frustrating because of the lack of low end torque. The super low case let me do very slow technical crawling with an engine and transmission combo not suited to that kind of driving. While I didn't use it a lot, I did use it and wasn't sorry I had the option.Have you ever driven anything with a 10:1 low range? Even with the manual that would be silly.

I get it, but 1st gear on the JL is significantly lower than the JK manual was. There comes a point when your crawl ratio just gets silly. With the 4:1 transfer case and 5.13 gears I'm well above 100:1. Even with stock gearing you'd be looking at a crawl ratio of well over 200 with a 10:1 case. I still argue that 4.3 or even 5 would be the sweet spot.There were several obstacles where the 4 speed atlas in my JK in compound low was an advantage.

With an automatic that has a higher stall torque converter lets you get the RPMs up where you need them to crawl. So I wouldn't put one behind an automatic. Not that deep. But that's just my own use case.
Just because you don't feel a need for it doesn't mean it's not useful to other people.
Mine was just a hair under 238:1. And I used that from time to time doing technical rock crawling. Not all the time. Sometimes I was in compound low in 3rd or 4th gear. But being over 100:1 does have it's advantages.I get it, but 1st gear on the JL is significantly lower than the JK manual was. There comes a point when your crawl ratio just gets silly.

Which is why I asked if he had any experience with a 10:1 case.Mine was just a hair under 238:1. And I used that from time to time doing technical rock crawling. Not all the time. Sometimes I was in compound low in 3rd or 4th gear. But being over 100:1 does have it's advantages.
Again, just because you don't use it doesn't mean it's not useful to someone else.
Automatic's have a huge advantage over manual, but even so 10:1 is way beyond silly. Invest in an auto, not a silly gear.

At 5,000 RPM you're going 2.3 MPH. Top speed of 16 MPH is silly.
My JLR auto rock crawls mostly in 2nd gear and I've never stalled it, lol.
I am on 37s and stock gears so far and 4:1 is too low for some stuff. Cannot imagine 10:1...I'll get my gears first.Have you ever driven anything with a 10:1 low range?
Please tell me someone has ordered this and has installed it?https://www.advanceadapters.com/atlas-transfer-case-jeep-jl-2sp-builder
Is this it? I don’t remember finding this last time I searched.
