Rc guyVerified owneron Yokomo Silicone Gear Differential O-Ring (Red) (4)

These are the o-rings that properly seal your Yokomo BD9/BD10/BD11 diffs from leaking. The included factory kit's clear o-rings are for max performance (minimal drag) but they leak badly. These red o-rings fix the issue for me. They keep the diff sealed and do not introduce any additional drag that I can tell. Not sure why Yokomo did not include these in the kits.
