Hot Racing Arrma 6S 29mm Modular Aluminum Differential Case
Do not buy this diff case for your kraton exb or other exb with the 29mm case! I've wasted hours on this as when I fit it back in the truck and screwed the plastic cap on that keeps the centre diff in the entire drive train locks solid! Hours of stuffing around only to find on the Arrma forums this is a common issue with these! I have the standard plastic diff mount and my truck is only 5 months old. The hot racing case doesn't have a raised section on hat like the factory plastic unit so what happens is the red anodised end rubs on the plastic mount. Waste of money! Now I'm off to get the Arrma unit.

Hot Racing Arrma 6S 29mm Modular Aluminum Differential Case
The quality of this diff cup is outstanding and I love that it does away with the paper gaskets and replaces them with rubber o-rings. They even give you a spare one. They fit the exb cars and the limited slip plates. Only issue is, they do not fit in the center diff mount without modification to the mount itself. I had to put shims on both sides of the diff behind the bearings and also shave away material on the insides of the mounts to allow the diff to have room to spin freely. Not too big a deal if you have a rotary tool. But this should be something that should be addressed by hot racing or at least noted in the listing of the item...
