    After Market Pistons on a Pro stock FZR

    I know people are boring and using after market pistons that are stock class legal. What are my options?

    if you are running stock class you can run aftermarket pistons but you cant change the compression ratio it must stay as OEM

    As long as your compression remains stock you have a big selection of pistons. Riva, CP, JE, etc. You can see your choices here in the forums online store
