E Revo Center Diff questions and Opinions - RC-Monster Forums

The gear you ordered is for use in a 3.3 revo tranny, you need the gear from the traxxas CD or use the original one and mod it for use with the Erevo trans. Also look on avid rc, and the bearing you find is the 8x12x3.5, and it will work just fine. Thats what I used and it works great.

So Can the Traxxas Center Diff hold up to the power of the Castle 2200kv Motor on 6S?

How dare you ask us not to hijack your thread!!!!!!

Go for a hybrid CD if you are going to use one. From what I've read the Traxxas CD will unload way too much to the front, especially since you'll be running 2200kv on 6s. The hybrid CD will handle the power much better. The Traxxas CD may be able to handle the power you're going to give it, but I think you'll have a hard time getting it to function how you want.

I take it that it comes with oil that is waaay too thin?

What do you suggest the diff be filled with? I could fill it with bearing grease or something really heavy. LOL

This might also help with the leaking problem.

It comes filled with 500k, and people still say that's way too thin. The problem is it only has 2 spider gears instead of 4 like in normal 1/8 diffs. Less gears means less ability for the viscous oil to apply resistance.

People have tried all kinds of diff lock greases and thick stuff in it. I'm not sure how successful they've been though. It sounds like 1/8 hybrid is the way to go if you want a CD. I'm only speaking from what I've read, but once I build mine I'll let you know how it works.

Not to argue w/you Jason but the CD comes w/100K, I had to buy 500K to refill mine and it was much thicker than the stock fluid.

I'll have to ask mistercrash. I ordered the exact part number he gave in his build thread.

EDIT: I'm almost positive it's the right gear (TRA3984X) but you just need to modify it quite a bit. The other gears can be used, probably with less or no mods even, but I'm following mistercrash's instructions exactly. There might be a reason he chose that gear instead of the other CD gear. Waiting to see what he says.
