The highest gears you can get are 3.90s. It is a VERY stout axle. I would compare it to a Dana 70, as far as strength. I have one in my '68 3/4 ton. The only thing that I don't like about it is that they haven't been made since 1972, and the parts availability is limited... including higher gears.

I have 4.57 gears in mine. Someday I'll get ambitious and either change them out to 3.90s or put a Dana 70 in.
