The Strongest Savage Diff Compilation.

[JasonB]

Yea, if you want a direct drop in option, the Boca bearing with the stock Flux cup may hold up just fine, or you could try the Hot Bodies cup.

If you want to save some money and still have a tougher diff, you could just put the CENs in the stock Flux bulks. Of coarse, this would not be drop in.
