Does anyone know what kind of gears come stock in a 97 Montero SR T Case? Just want to know how much of a difference 3.15's are from the stock gears. I am assuming that these 3.15 gears would work in my 97 Montero SR with auto tranny??? Is this the lowest gear ratio available for my 97 Montero T case?

What about diff gears? I have heard that I can get gen III diff gears from a dealer and have them put right in my gen II diffs and it will lower the ratio? is this a good idea? does it work well? by how much does it lower your diff gear ratios?

The larger T-case (94+ SR's, 95+ LS, Sports w/ Auto's) has a 1.90:1 low range and the smaller T-case (almost everything else except Gen III) has a 1.925:1 ratio. The 3.15's will lower your T-case gearing by about 40%.

As far as diff gears, do you know if you have 4.636 gears or 4.272 gears? There was a change somewhere around then to the higher gears. Either way, if you look in the part number repository (stickied at the top of the Tech forum) you can find part numbers for 4.900 gears from a Montero Sport. These are as low as you can go in the SR. Going from 4.272 to 4.90 will lower your gearing by about 15%. Changing both the diff gears and the Tcase gears will really make it crawl slow. Your overall crawl ratio will change from 22:1 to 43:1.
