I know that there are a few like 1.002 (?) and 1.222 (?).

What kind a difference could I expect changing these two?

My RRC is at 3000 RPM doing 100KPH (60MPH) and I have the 1.222 gears.

( I know that my diffs are geraed too low but I do enjoy the good low range that they offer- d44s with 5.13-more get up and go is nice off the start but thinking about the driveshafts on the highway makes me kind of sick!!!!)

Input ya digits and it'll spew out the knowledge you seek. Unfortunately all the charts below are for jeeps (god damn jeeps) but you should be able to make something work.

yep that's the one- i'm trying to get the link from LR4x4.com at the moment as i would like to be able to attribute it. It's far far far more useful than any other calculator i've seen so far.

if you know the link can you post it up here- if not i'll send the file to anyone that pm's me.

Right found the link had to ask someone else).
