Replace a Rear Spool for a Rear Diff in the EMaxx? A good idea? - RC-Monster Forums

Sorry to make a new thread, but:

Would it be worth it to get a rear spool then messing with the diffs?
I know I keep changing my mind, but it just popped into my head.

Maybe something like this:

In this case, I can still use the 3.3 diff housing, and just replace the diffs, with the spool, but with the same cups/housing thing right?

If you think you have diff problems now, just wait till you get the spool put in...

Oh boy.....

So basically the spool would cause.... much more problems?

Spools basically appeased those who wanted to do wheelies with thier stock emaxx's. Nothing but trouble for me....

Alright, thanks guys, guess it's back to the shimming the 3.3 diffs with aluminum housing/cups...

With a spool you still should shim the ring+pinion, which iirc was what you were stripping. You're just getting rid of the diff cup and spider gears (and making the truck harder to turn) with a spool. Unless you're running only dirt and like on throttle oversteer, or really like wheelies a spool is not a good idea.

Al housings (case) will help with the ring and pinion stripping, as long as you shim correctly. Al cups will help if you have issues with the diff internals. Given the 2 spider design and the power level, al cups are mandatory to help the spider gears survive. The single crosspin in the diff takes all of the truck's load if both tires have equal traction, that is why the pin wears the plastic cups.

You have quite a few options if you stick with the 3.3 diffs. The 3905 diffs are different and there are no as many companies making parts. Plus you may be able to find some 3.3 cases and cups used, not like they will wear out.

So, then... I should be looking at the ERevo 3.3 diffs then?
Anyone have a guide for simple shimming? I'm stupid on diffs and whatnot, or just stupid completely.

Also, anyone have any used al housings? Overdriven, you have a PM.
