This is a pack of ten replacement O-Rings for Mugen buggies and trucks, and fits the Mugen MBX5 buggies as well as the MBX5T trucks. These small O-Rings are used in the differentials to seal the differential outdrive shafts to the differential case to stop the silicone diff oil from leaking from the buggy.

These also fit in the Losi TEN-SCTE / TEN-T differentials, in the hex pieces over the outdrive shafts. They seem to fit slightly more snug than the stock Losi o-rings. TBD (for me) if they seal better.
