This angryBuddha actually became happy because he installed these awesome Fonzon fully assembled diffs into the Arrma/Losi Grom vehicles. Why is he so happy now, well let me tell you. He no longer has to worry about the diffs failing due to heat and leaking because the entire assembly is enclosed on a 7075 differential gear housing. In addition, the super strong housing keeps the pins of the gears in place with less deflection. Unless you are doing donuts with your Grom vehicle for the entire battery pack, I'd recommend this item for all out bashing, and on a side note should any internal spider-gear or sun-gear becomes sloppy you can always put the original Arrma gears in them.
