Mugen T0244 S5 O-Ring

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.
