the case is I have a lot of 48p stuff that i used on my TC5 and i don´t really want to change for the tamiya one.

Not a problem at all. I run 48 pitch. FYI, the biggest spur you can use would be an 81T.

Which ceramic balls are consider reliable. I brought the CDB-3 but to my dismay the reliablle not as good compare with original tamiya steel balls. Eventually after few runs I got cracking sound on my diff. Although after service prob still persist. After replacing with the ori Tamiya steel balls all fine.

I've found ABEC35 ceramic balls to be inexpensive and durable. I've been using them in my 416 for about a year and a half!

Yes you can.. I did it for mine. The spur provided by Tamiya is too soft not durable. I replaced it with Yokomo 48p. It lasted me much longer fun time.

Tamiya has ceramic diff balls as well, part # 42142, very high quality, built a diff with them a week or so ago and it already has a ton of track time, still feels perfect.

Thanks Randy never thought of that. By the way they also have tungsten balls. How different is tungsten balls vs ceramic balls.

To what I knew ceramics surely lighter,

Tungsten is middle of the road. Lighter and harder than steel, softer and heavier than ceramic.

Tamiya does sell ceramic now too (Tamiya 42142):

When your diff starts to get blown out, you will notice it is most crunchy at the end of the run. This is because the metal expands as it heats up. With the ceramic balls, they will not expand with heat, so even as your diff is starting to go out, it will still feel fairly good.

The other nice thing about the ceramic balls is they are very wear resistant, so you can actually replace the diff rings while re-using the ceramic balls and your diff should still be smooth for at least 2-3 rebuilds.

Atomic make a set specific for the 416, but they are a little disappointing for durability.

I don't remember where I got them from thou, maybe HK Hobbies.

It's frustrating to have a diff that won't stay smooth. I have used a few different brands of ceramic diff balls before TRF introduced theirs, I feel that they are very competitively priced, and worth spending the extra few dollars to have a diff that lasts.
