    QUESTIONS & ANSWERS

    • Q: ringland failure  weechie444 years ago

      will this help prevent the ringland failure? which every subaru has a problem with lol
      • 0 of 0 people found the following answer helpful

        A:  Absolutely! Installing forged pistons and the surrounding components (rods, bearings) will help strengthen the internals and catastrophic failure. Thank you.

        A:  CP does not have an official horsepower rating for their shelf pistons and they said that the power rating depends on your parts combination.
