Rustler extended CVDs 6mm axle?

Is this true? Do they include new bearings? I saw this in a description of them on another site, but the picture didn't show any bearings. Id like to know if its 6mm for the entire length of the axle, meaning maxx sized hex hubs and hex adapters would fit. I see that they include new hex hubs, but I don't know if thats because the stock ones wont fit or because they wanted to upgrade them to aluminum. Thanks for any help.
