RE: hyper 7 busted differential
If you keep the diff gears shimmed right those bushing shouldn't come loose, I guess that's what you're talking about. I've been running thew hyper chassis for almost 3 years and haven't had a diff case come apart
From your other post, you're still running the old style a-arms?
wow, those came on the original RTR kit are you sure you have a pro kit?
