What's a Good Replacement Rear Diff for the E-Maxx?

[Unsullied_Spy]

Aluminum cases and shimmed gears help a ton. With the new I-Beam diffs in aluminum cases (aluminum cups can help, but definitely get the cases) you shouldn't have a problem with them. Most Ring/Pinion strippage is because of the stock plastic cases which flexes under power which throws off your mesh and screws your gears over. Aluminum cases don't flex under power nearly as easily.

I think the LST (or perhaps Muggy) diff mod is the best way to get bulletproof diffs on the cheap, with the aluminum cases those things are tough as hell! I'd like to see Ofna Spider diffs in a Revo though (pretty sure the 8 spider UE diffs are rebadged Ofna diffs but I'm not totally sure).
