Anyone else have problems with the Revo shock ends popping off, the plastic end that screws onto the shaft? I have two Revos and this has happened on a rear shock on both of them. Luckily I was able to find the loose parts in the dirt both times it happened and put everything back together. I don't know if they are unscrewing or popping right off. I see that Integy and Golden Horizon sell aluminum replacements. Integy's has a locknut; Golden Horizon's does not. I'm thinking of getting a set from one of these companies but don't know which one or if the locknut is necessary. Can anyone help?
