New Flux diffs in a few weeks !

[Unsullied_Spy]

Nobody that I know of runs them in a Savvy, but I have Muggy diffs with the LST aluminum cases in my Muggy and they are bullet-proof. The LST XXLs have aluminum diff cups as well as the cases but my Muggy with the plastic cups has been exceptionally durable. When it comes to stock diffs, you'll be hard-pressed to find ones tougher than these Losi diffs and they can be had on eBay for $20 or less.

From what I have researched, if they were as strong or better than the CEN gears, I think most guys would be using those as the upgrade instead of the CEN ones.
