    5 Speed rear diff?

    im going to be doing a 5 speed conversion sometime in the future and was woundering what the best rear diff would be? i have a 4.10 right now..could i use that one or get a different one?

    Quite a few people swap out their 3.73 for a 4.10 actually.

    I'd say do the swap, leave the diff in there, and see how you like it.

        4.10 lsd or 4.10 open? Either will work, but if you can swap to an lsd.

            there should be a metal tab on the rear cover of you diff that says 410 and it should have an s on it. Also if you have an auto IS there is a very good chance it is an lsd. I have a 4.10 that I swapped from my 3.73 and I love the tourque it gives, but at 80 mph I run @ 3600 rpms, that's a bit high so I don't really speed anymore.
