Terra Flex LOW 231 kit?

Does anybody have the Terra flex 4:1 kit installed behind their AX15? I am also wondering how hard this would be to do myself? Or any other options out there to get a 4:1 or higher T-case ratio that you guys know of? Aside from spending a few grand on an Atlas II.

Tera Flex LOW 231 HD Transfer Case - 23 Spline Long Input (2104200)

Easy to do yourself. If that's a whole t case. Pulled mine changing clutch for fun. And to learn. For when I buy an SYE. It's in this video if you want to skip to it. http://youtu.be/BS4abyp0zfk

I suppose it's as easy as installing an SYE (which IMO is easy )

You can't go above something like 20mph in 4lo with the teralow kit because it starves the planetary gears of oil or something like that. I have been looking for a 241OR transfer case from a Rubicon to swap in. Its a stronger case with 4:1 and a fixed yoke stock.

That you can't drive faster than 20 mph in 4Lo is due to that causing the gears in the planetary to overspin. Which is no big deal since if you can drive that fast, there's no need to be in 4Lo. My best advice is if you're wanting to shift from 2nd to 3rd or higher while in 4Lo, it's time to shift back into 4Hi or 2WD.

I have definitely considered the NP241OR. It would be way easier to install as well. the problem is finding one. Do you guys know of a place to find them? stealership?

Though a great tcase, the 241or is not a bolt-in either. And if talking new I have no doubt an Atlas would be cheaper than a new 241 from the dealer.

What would have to be done to make the 241OR compatible?

Rubicon transfer case swap, what all is involved?

It can be bolt in depending on your year and current setup (body lift/TC drop).

You do have to get 1310 yokes put on or simply using 1310 to 1330 ujoints no matter what

Ok, so what years are direct bolt in then? I have a 98 with the gear style speedo. I have 1inch BL and 1inch T-case drop(not by choice).

I'm running the Tera low 4:1. And love it. It's great for crawling and can save a lot of wear on your clutch. Install was easy but I did have some experience rebuilding a 231 Tcase and installing an SYE... And as stated above you won't be able to move very fast in 4lo. However what's the need. Go to 2 or 4hi...
