44/9 or 44/60

A 44 with RCV's is plenty strong enough for 37's. You will brake hubs before anything else. My 44 with chromo shafts and joints has held up just fine with 37's.

through some drive slugs in with those rcvs and it will hold up alot better.

cryo the gears. then if that doesnt work.

through some d50 gears in there to beef it up.

i run ford d44 up front and ford d60 rear on 35s and have no problem locked up. the only thing about a 60 is that you might want to run atleast 37s because i get hung up a lot on the diff with 35s

This looks promising if you want to keep the streetability of the manual hubs.
