I had an MBX R2 and it uses the center diff that carries the 51T spur that we all use on the Strobe slipper for the emaxx. It also uses some odd size bearing. I cant remember the size but it was different than any other buggy I have seen. I would find out the bearing size that is used in the MBX R2 and the Jammin before buying. I also doubt that the screw holes will line up just right.

For my MBX I just used an aluminum angle mount. It was stronger than the buggy... Which isn't saying allot unfortunately.
