Will also work with the Arrma Typhon 6S center differential. Currently use this 40T spur gear in my Typhon 6S TLR w/ a 34T and 36T pinion on an M2C Racing mount. Can also be used with the stock Arrma mount just can't use as large of a pinion gear. This spur fits both the stock Arrma plastic diff housing and the 7075 aluminum center diff housing. I actually recommend using the 7075 housing with this spur.
