I actually heard of KWA 2GX parts being used in other brand gearboxes. Even then, it's tough to say because believe it or not, many brands are not cross compatible. There's a little more that goes a way than just a part "fitting" into a gearbox. When parts are made, they are made to a dimension that a manufacturer or company specifies. If a gearbox is too thin for the KWA 2GX gears, then it will not fit. If a gearbox is wider, well, then KWA gears can be shimmed into it. Then, there are other factors to look at, as well, like how certain gears, or various parts of the gearbox meshes with each other, and the materials of each part.
