Need help with choice of 1/8 scale diff for E-maxx

[KMN]

I have run the Kyosho diff's, the Hot Bodies Diffs, and the OLD Hot Bodies diffs.

The Kyosho diffs that will fit are from the ST-R/ST-RR/ST-RR Evo/MP7.5/MP777 series of 1/8th scale vehicles. The choices are pretty standard, just make sure you get the right pinion based on the diffs. The teeth can be had in both helically cut, and straight cut. eBay is a great place to find these, but you are going to need the 8mm outputs on the pinions. For the Hot Bodies, the diffs from the D8T/D8/Ve8 are helical cut teeth. The best part about the Hot Bodies diffs is in the pinion. It is cut down to 5MM from the 8mm pinion bore so you can use pretty standard driveshafts. MIP makes 5mm/6mm bores and all of their crawler driveshafts are usable with their Maxx based shafts.

As for which one to buy, both will hold up very well. The older Hot Bodies stuff (Like form the old Lightning buggy and Lightning Stadium truggy) have weaker internal gears. I have not even seen these for sale in over 7 years now, so no real worries on it, but they are the only ones I've manage to mangle and break with relative ease.
