To be honest there is not much to say about the hpi diff gaskets. They are what they are and do a very good job of keeping oil in the diffs.
This is more to say what a great company RC Geeks are and the level of service you receive is second to none. Always polite and friendly and always go out of their way to help in anyway they can. I have always had great experiences with the company and I continue to support them by purchasing all my RC need through them.
RC Geeks is definitely a seller to trust.
