Default wj crd and rubi crawler ?

Now that we know a JK 07-11 TC rock track 4:1 fits well our wj crd,
Did any one considered a rubi crawler adaption between the gear and the TC?

The ratio would be 7.3 vs 2.7 - a bit too harsh for the drive-train, yet i would go for it.

Here is a the crawler:

Note that the tc side will probably match as is to the 247 TC, the question is length and the gearbox side match.

On the 2.7 CRD it will cause transmission slip errors, because of the way the TCU uses wheel speed sensors to monitor output RPM.

No electrical isseus when matching 4:1 rubi tc in low gear. Thus no electrical issues for other ratios, given that u r in low gear position on the tc position sensor.

Btw, i have no sensor hooked, only a switch with proper resistores in the cabin.

Again the question is mechanical only

You can get an ABS filter from jeepswj.com and configure it to whatever ratio you want for the axles and the transfer case

The rubicrawler box probably won't fit as it's designed for the 42RLE transmission unless the adapter section on the NAG1 has the same bolt pattern as the 42RLE.

No need for an adapter. In low gear there is no cross check. again, rubi rock track tc 4:1 is working fine out of the box on our wj crd. I guess this is a new information for most of you guys, I would expand more this, but the credit and the details are not mine.
