About this part

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.

BUT THESE O-RINGS ALONG WITH THE GMK HARDENED SHIMS FOR THE TEN-SCTE AND GLUE IN THE INSERT WITH CA AND LEAKS WILL STOP.....PERIOD!

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.
