QUESTIONS & ANSWERS

  • Q: ringland failure  weechie443 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.
