  • Q. There is two piston rings and a thin ring. What is the thin ring for?
  • A.

    Hi, it can go underneath one of the piston rings to increase the pressure of the piston ring against the cylinder wall.
    In theory this gives a better seal but the disadvantage is more friction (less power) and faster wear.
    Most people would not use it and discard it.
