The Strongest Savage Diff Compilation.

[_dV]

Well, for starters I don't know what I'm doing wrong (or right). I have only ever run the stock Flux composite bulk and stock bulletproof diffs without any bearing or gear breakages. I've always run heavy silicon fluid in them (50K-100K) and haven't used any really heavy wheels or larger\longer can motors than stock, so that might have something to do with it.

Diff Case - I have a Vorza center diff and the case is a composite but felt very stiff. If these cases work it would be great as it also avoids loctite\silicon fluid in thread issues.
An alternative to a different case might be to just use a high quality ceramic bearing for the 10x16x5.

Spider Gears - again have never damaged one but would be nice to have a stronger option. Haven't heard of any other options.

Diff Case Screws - Hex heads are heaps better than stock. Have been using some that were in my Tony Screws kit.

That said you can still damage the head and it would be great if somehow a larger screw could be used but that's unlikely. With the plastic case I have wondered if I could drill right through the case and put a lock nut on the one end. Probably not enough space in the bulkhead for that though.

What I would really like are harder outdrives. They are what wear on me the most where the dogbone pin rubs.
