Well this little gizmo is ment for the JK's with the 42RLE tranny,which is a zero modifcation and bolt on,but I can't see why it won't be the same for the KJ with the 42RLE,might also work for those with the 45RFE and 545RFE.You simply remove the rear tranny to t-case adapter and bolt this baby inbetween the stock(or aftermarket t-case like the AtlasII),adding another 2.72:1 reduction,so if using the stock t-case it'll drop you to 5.44:1 low range,and your not needing to modify your driveshafts or anything.In theory it will work on the KJ's also,just a thought.

Are the stock tranny to tcase adapters the same on 42RLE, 45RFE and 545RFE? You'd think so, but....

Not a new idea, just a new mfg/vendor and some new applications.

It would give you basically a 3 speed t-case..............

1:1----RubiCrawler set to 1:1(hi) and t-case set to 2hi or 4hi
2.72:1----RubiCrawler set to low(2.72:1) and t-case set to 2hi or 4hi,RubiCrawler set to hi(1:1) and the t-case in 4hi
5.44:1----RubiCrawler set to low(2.72:1)and the t-case set to 4low(2.72:1) for a total of a 5.44:1 low range

It also will give you the option of 2wd(rear only) low of 2.72:1.

I think both in low is actually 7.3984:1 I'm pretty sure you multiply, not add when dealing with gear reductions in series.

(probably going to be banished to driving a honda for this question).
Is there such a thing as too low? Will the drive train be able to handle such a low ratio?

Sounds a lot like a "Klune" to me...

Yes. Sometimes your brakes would not be able to slow you down while in gear...or...you start to break things...but that is the fun part about it...lol

There have been times I found 4:1 / 1st gear too low on my KJ. I Often am running 4:1 in 2nd & 3rd which works well in many situations.

But the Klune still extends the length of your driveline. The Advance Adapters unit claims no additional changes in the length of the driveline.
