Default Spool diff for TC3?

I'm pretty sure no one makes one of these, but could I simply lock the stock diff by drilling holes and bolting the two sides together to make one?

the factory spool was crap anyhow. i used to lock my diff by replacing the balls with a thin o-ring on either side of the diff gear that fit to the rings.. worked sweet..

You couldn't because it would crack under the pressure of turning. I have a spool in my TC3 and ran it for a few seasons and no problems whatsoever. I even went through a few sets of CVDs because it was so strong!

I'm running XRAY now and have the spool laying around. If you are interesting in buying one, send me a PM. I think they are normally around $40 new.

Just use diff putty if you want to lock the diff. RC crawlers use it.

If you are using the stock plastic/composite diff halves they can break very easily using them as a locked diff (spool).

Either

1) allow minor slippage like others have suggested (but they may melt)

or

2) go for your wallet and get the metal outdrives and lock it tight.
