He is putting in lower gears so it doesn't matter what gear ratio the open diff has, although it will most likely end up being 3.73. It will be cheaper to ship without the heavy ring gear on it anyway.
In addition to being cheaper to ship without your ring gear, you will probably be wanting it unless you are doing a gear swap yourself. You aren't supposed to mix and match ring and pinions because they are a matched set lapped together at the factory. Just thought I'd throw that out there, since no one else had mentioned it, in case you weren't aware. Don't want somebody coming up with a rear end rebuild expense they weren't prepared for...

That's not true, nothing is "lapped together" on it. They just cut them all the same.
I never mentioned any 10.5 etc. ................read, and what argument?
Ok, so we where taking about a 10.25/10.5 carrier..... This is how it went not?

I'm not sure where you where going with this, unless you where changing the subject from the 10.25/10.5 rear ends that every vehicle in this section uses to rear ends in general. Either way, idk why I'm even bothering responding.

You added AKA 10.5 etc to my statement in red (putting words in my mouth) but when I said THOSE I was referring to rear ends in general, "those rear ends" like "those v-8's" etc. I have no idea about certain ones or years. I only said they (meaning rear ends in general) never used to have rings.
That's not true, nothing is "lapped together" on it. They just cut them all the same.
With all due respect, as I have seen much of your advice that was great and right on, I think I personally have to differ here. However, it's not my rear end or my money, so in the end I don't care which ring gear he uses. Just seems to make more sense to use his own.
Technical Help
This guy LITERALLY wrote the book on rear ends, so I have to believe at least most of what he says...
All of my research and every trans and gear mechanic I have talked to, says that they are. However, knowing mass production, say you are right and Ford doesn't manufacture their ring and pinions like every other company who does lap them. The fact that they have been driven would have worn, or "lapped," them together. I have heard of guys mixing and not having problems, but it was always almost new gears. I know after rebuilding a rear end twice in a month because the guy I was doing it for wanted to try and cheap out and use a used ring gear from a junk yard (right rear end, right number of teeth, double checked), I will never do it again.

Ring and pinions are not lapped, they are made to certain specs and then case hardened which is extremely hard and can't be lapped anyway. It's a myth, nobody is going to take time to lap any production type gears in. They might be matched during the machining process somehow but I don't know about that. I read that guy's TECH HELP and I only agree with about half of what he said. Unless you have built hundreds of rear ends there is just too many myths associated with them. I can't really take anyone serious that uses an air impact to crush a sleeve........lol (You can approach the optimum bearing load at any time). I would like to critique all of that guys' statements but it would take too long.
