I bought what was supposed to be a 3.73+ carrier for my 4.56s off of craigslist, but next to the old carrier, I can't tell a difference between the two (other than the old one was covered in oil, new one was clean). How can I visually tell the difference between the two? I'm worried I was duped.

Secondly, I was taking out the nuts of the ring gear from the carrier so I could install the new gears on the other carrier, and stripped the threads on one nut from the carrier. Where would I go to purchase a new carrier bolt? I tried the local hardware store rout last night, but I wasn't confident in the selection nailing the exact size.

If you have the two carriers side by side on your bench, the hi-ratio carrier will have the position of the ring gear flange slightly more toward center (like ¼" or so I think).

hmm, I'll have to go take a look. Thanks for the info. My memory says the flange is about in the same spot, but I may have to look closer.

So yes, I confirmed one had the flange slightly closer to the center. It appeared to be closer to an 1/8" visually. Thanks again.

Now onto the ring/carrier bolt. Any clue where to turn?

Your gear installation kit should include a new set of ring gear bolts.

well from the hardware store anyway....I found some that were same size in all dimensions except milimeters longer. I've hacked off nuts before, but this is not a place where I'd feel comfortable doing such a thing. A ring gear seems to have more of a "precise" feel to it than other tasks I've done in the past. I'm going to go out and check out my master install kit. I've had it for months and never opened it. I was just under the impression it wouldn't have something like that.

I did find though that ringpinion.com sells the bolts. I might replace them all if they're not in my master install kit.

Thanks for the help y'all
