Diff Gears and Upgrade
I found this page:
I'm kind of confused, will the 4.11 gears and the 4.33 gears fit in a standard diff without upgrading anything else? What is meant by thick gears? Is 4.33 the biggest that you can go with a stock diff case?
Also while I'm in there should I rebuild the diff? Beef it up? Or are C3 diffs pretty stout? I plan to use nitrous in the near future and I have a manual trans but I won't be using slicks.
I saw some Posi Units on Van Steels website, 3 & 4. Is the 3 a stock style unit and the 4 a posi unit that accepts larger gears like 4.56? I'm lost.

The thick gears mean it can be used on a 3 series carrier. Otherwise you will need a 4 series carrier to run a 4.11 or 4.56 or anything like that.
Yes the 3 series will run a 3.08 to a 3.73 GM gear or a thick gear 4.11 or higher. The 4 series will run a 4.11 or 4.56 NON thick gear.

better yokes?
sorry to thread jack, but can you explain the differences in yokes? I have my car at the mechanic's with a diff rebuild and am waiting for the Ecklers to get in the yokes which have been on back order for 4 weeks. I do plan on driving my vette like I stole it once it gets out of the shop so can you elaborate on the better yokes?
I think these are the yokes he is waiting for....

Thanks....
btw...the diff was an original 4.10 and now is in the process of being rebuilt into a 3.70 to match up better with the new 6 speed richmond tranny that they have installed if this helps any at all. I saw the old yokes and they were definitely shot needing replacement.

So to me spending $2000 on a rear end is cheaper in the long run. At the time they didn't have 12 bolts or I would have bought it.
