wanting to bomb proof my brushless racing emaxx

1. Which gears are you actually stripping exactly?
2. rc4wd.com sell a full set of alloy tranny gears that should solve your issues internally with the tranny atleast (they wont sell the individual gears as I already asked, but they did give me a $10 discount atleast on the full set).
3. RCM doesnt sell upgraded maxx diffs- I wouldnt waste your time with alloy cups and cases for the stock diffs as it doesnt always fix the issue, which is weak spider gears.
4. Unlimited Engineering sell 1/8 scale diffs for the maxx, check ebay for a pair of the Ultra Lite 6 spider diffs, should cost about $160 or so, best you can get for the price.
5. It is possible to modify some LST diffs to fit the maxx bulks, much cheaper than UE option but requires a little bit of work:
