  • For street, bracket racing, and oval track applications, these aluminum hypereutectic pistons feature an antifriction skirt coating that is highly resistant to scuffing and wear. They operate with tight bore clearances and work perfectly with normal ring end gaps.

    Note: All compression ratios are approximate and figured with a gasket thickness representative of those commonly used. Pistons designed for floating pin only applications include lock rings.  The ACP/DCP series pistons are designed for pressed or floating pin and do not include lock rings.


    • Helps improve cylinder sealing for less blow-by
    • Retains standard ring gaps in top groove
    • DUROSHIELD skirt-coated piston
    • Moly-graphite coating extends engine life
    • Reduces friction for higher fuel economy
    • Prevents damage from inadequate lubrication on startup

    How much compression would it be with my heads Combustion Chamber Volume 64cc ?? Thanks

    Asked by: Armando
    The compression ratio would be near 8.5:1
