So let me get this straight:

The crawler gears will only affect 4-Lo performance? So if I have 33" tires, my highway speed/fuel economy will remain unchanged with the calmini gears? Whereas if I get the new R&P (front and rear), my highway performance will be better with 33" tires, but my crawling speed won't be as low as with the calmini gears? How big of a difference are we talking in 4Lo between the two options? Any idea how much lower the gearing would be with the R&P over stock (with 33" tires)?
This is an email from AC regarding their R&P for anyone who is interested:

Quote:
You will need 5.14 gears front and rear. If you only replace the rear ring and pinion set and place your Xterra in 4x4 position you will damage drive shafts or the transfer case. You can replace the rear first as long as you do not use 4x4 until you install the front ring and pinion. The rear unit is sold for $625.00 and the front unit is sold for $450.00.
