6S is fun, but the truck requires some upgrades to handle it reliably. Problem is, you'll be changing diff ratios (2.85:1 to 3.31:1) so you'll have to regear some.

If you explode the diffs after that, your only option is the RC-Monster Hybrid diff cases, and those take 1/8 Scale diffs. Integy, GH, and HR all make diff cups that take the regular M2.5 screws that bolt up to the original gears, however. FLM makes these for the Revo & Maxx, and they include a modified ring gear that takes larger (M3) screws to boot. If you blow the spider gears (cup comes apart) later, you can fix that with an aluminum diff cup. The rear diff takes a much harder beating than the front end, so if you're strapped for cash, doing the rear end first is an option that works. Replacing the differential cases with aluminum cases will solve most diff issues you'll run into. This is a problem on both Traxxas Monster Trucks (Maxx & Revo). The problem is that the differential casings (plastic) flex under load and allow the ring and pinion gears to change mesh, which blows up the teeth, as you've no doubt already seen. Any suggestions or clues as to why? Is 6S too much?Īnything helps! Thanks!!!The stock differentials don't really hold up to 6S, no.

I keep having problems with the rear diff. Im running the mamba monster system on 6S. Got an E-Revo a few months ago and finally got it all put together.
