Cool Beast...Ask Bruce if he is replacing the "Seal Head" it's the main part that has to do with our shocks leaking. It's located at the bottom of the shock where the shaft enters the shock and that seal is the one that fails, also just changing that seal might be ok for a while but if the bushing is worn it won't be long until that seals fails. We found what we need through KYB mainly the Seal Head complete unit (16mm I.D X 46MM O.D.) We disassembled one today and I'll have pic's tomorrow showing the Seal Head. And there wasn't any scaring of the reservoir I.D. or the main I.D. of the shock body...
