Can a sport t-case be upgraded with 4 to 1 gears

I've got a 2012 jku sport with auto and was wondering if I can do a gear swap and make it a 4 to 1

Drop in a Rubi transfer case?

I believe you would have to swap out the whole t-case. That's what I did

They are the same t-case just different gears are they not?


If you don't push the limits how do you find them??

The planetary gears would need to be replaced and the front half of the case would need to be changed but, yeah, you can technically do it. Having said that, replacing the whole thing with a Rubi case would be easier and probably cheaper in the long run.
