Why not get low.. 3.92:1 low.

Follow up:

First off I did not reuse the stock Tcase. I had one that was pulled from an early 90s Pathfinder. WHY??? Well the chain in the Xterra Tcase is not as strong as the Pathfinder Tcase. Basically the Chain in the Pathfinder Tcase is 3/4" wider than the Xterra Tcase. It bolts right in you just need to change out all 3 sensors on the Passenger side of the case.

High Points

WOW... I really think that this mod is NOT talked about enough. The amount of control it gives you is awesome. The power is by far a huge improvement over stock as well.

* The gearing!!!!
* Control is much better when crawling up & down everything.
* The ability to just nearly idle up things is great.
* Much less momentum is needed to get up things since you can allow your tires to spin really slow to grip the terrain instead of spin off.
* Much easier on the whole drive train by not needing to generate the momentum.
* Much easier on the Transmission and Engine, you can feel it not needing to work as hard.

Negatives

* Needing to grind down portions on the inside of the Tcase.
* The new gearing is a little too low for flatter portions of the trail, but honestly that does not bug me.
* The new gearing is so different you will have to RELEARN how to drive it. It changes it that much!!
* Using a Pathfinder Tcase you have make a linkage between the Tcase and shifter.

Would I buy them again?

Yep and I would do it much sooner than I did now that I know.
