what is the gear ratio of a np231 transfercase in lo and what would thecrawl ratio be with 4.56 gears this for a 92 yj with ax15 manual trans

2.73 I think.

3.83 x 2.73 x 4.56 = 47.68:1 ish.

those numbers are off the top of my head, I'm pretty sure they're close.

I prefer to use the Rock Crawling Index (RCI) which gives a better indicator of how your Jeep will perform... check out:

You mean all that time and $ spent on gears and I have this......
Calculation Results
Forward Crawl Ratio: 76.7136 : 1
Reverse Crawl Ratio: 92.5481 : 1
Forward Movement @ RPM: 1.4077327550949248 Feet/Sec
Reverse Movement @ RPM: 1.1671708285913615 Feet/Sec
Forward Speed @ RPM: 47.335954887897785 MPH

............I guess that I need to start saving for that NV4500 upgrade-it would give me a Forward Crawl Ratio: 123.7568 : 1
