Transfer case :)

Hey, so I'm wondering about transfer case ratios. Most of the threads I see that are about re-gearing are for the diffs. But, I also remember reading about the rubi having a different transfer case than non rubi. How come all the threads with people wanting gears and lockers don't have people wanting new transfer cases too?

rubi has 4-1 gear ratio in 4-lo and in 2wd and 4-hi, its 1 to 1. the non rubi has a 2-73 to 1 gear ratio and runs 1 to 1 in 2wd and 4-hi,, after market TC are big money, more than the cost of a re-gear,, i know there is a company out there that makes a gear box that bolts between the tranny and TC to give you half gears,,, some where between 4.1 or 2-73-1 .... its not cheep either. regear is your best option.


life is too short to be taken seriously all the time,,,, go buy a MR.potato head and have some fun.

The rubi crawl goes on the back end of an auto tranny replacing the plantery gears and gives you 2:1 reduction when switched on.
Most folks on this forum are not going to go trough the truble to do anything with the Tcase.
The ones that do tend to swap in a 2 speed atles. Iv got slightly difrent plans myself.

If you do a lot of crawling then a transfer case swap is a great Idea if you have the 2.7:1 case. A buddy of mine just put a stack 3 speed in his TJ and it made a huge difference in how much control he has on rocks. the 4:1 rubi case is awesome in rocks as well, ifmine ever breaks then I'll find an atlas 4 speed for it, but until then the stock one is doing just fine.

I found a Rubi TC from a wreck about 180 miles from my house. I grabbed that ASAP and did the swap and haven't looked back!!! Loving the 4:1 lo range ratio in the hills.
Happy Jeeping
