Dana 60 gear ID

I run spools on the street.
I do too. The o.p. might not want to.
O.P., best advice you will get here, is to call (with a phone) Dr Diff. He can help with gears ( I think you have a 4.56-up spool, so you MIGHT be able to go down to a special 4.10) and a lsd (sure grip or a true Trac, gear style)
If you want a more street friendly gear, you will probably have to replace the spool you have as well. Dr Diff is the only place I know of that you can get 3.23s for a Dana 60, cause he had em made.
