mugen diff

Not sure but i think you can place any 1/8 diffs and pinion in the RCM hybrid case.
But please, it's not my question !!!!!

I don't own a Mugen buggy, but just from looking through the diff parts available for them, it looks like the 46 tooth ring with the 10 tooth spiral pinion is an optional gear ratio.

It looks like it will work to me.

I haven't been able to find the diameter of that pinion shaft. It appears to be an 8mm shaft with a 6mm turned down end where the cup mounts.
