Have you guys tried to run them without any push back? They are so much smoother in operation and dont leak anywhere near as much. Also try putting kyosho xring seals in them. Let the springs do the work for you. The shock should have no push back if built correctly. They work better and last longer this way. You will have to rebuild them or fill them no where near as often. Have you ever watched Cavaleri or Mayfield do there shocks?
