    Details

    Keith Black Hypereutectic pistons are favored for their improved power and reduced scuffing. The unique design & manufacturing processes combine to produce a rigid piston, which will rock less in the bore improving ring seal. These T-5 heat treated pistons also offer reduced thermal expansion, which allows you to run tighter clearances and allows the piston rings to seal better and minimize blow-by.

    • 390 Hypereutectic alloy
    • Fully machined crowns and valve reliefs
    • Drilled oil drain backs
    • Full floating wrist pins
    • Triple wound spiral locks
    • Reflective alloy allows 2% power increase
    • Quench dome technology minimizes deterioration
    • Zero deck quench designs
    • Lightweight wrist pins
