this is for a '86, not sure if yours is the same, one of the zook guys will know for sure.

Gear ratios
1st 3.652
2nd 1.947
3rd 1.423
4th 1.000
5th 0.795
Reverse 3.466

Transfer gear ratios
Low 2.268
High 1.409

with your current 3.7:1 diff ratio your crawl ratio is

3.652 x 2.268 x 3.7 = 30.65:1 (pretty ordinary)

with your 4.88's you will have (30.65/3.7) x 4.88 = 40.42 (better, but still not great)

go the rock hoppers, better value for money and harder to break.
