[Xtreme*76]

the piston of regular OS 91 Cspec or Cspec PS is 29053210

91SX-H RING C-Spec Viper piston is new designed 29053220

Does anybody know where it is possible to buy it?

I don't think the new parts are available for sale yet. I know several pilots here in the USA that have ran the new piston. From my understanding the main difference is the piston is a couple thousands smaller in diameter.
