assuming 80 series? which engine etc?

standard is 4.1:1. it's a good ratio, strong and cheap to replace if you do break them. if you regear, lower ratio gears are more expensive and not as strong.

if you need improved crawl ratio, get transfer case gears. then you get to keep your tall gearing for the highway.

Don't forget, if you change rear ratio you have to change front as well... :cool: :cool:
