Flat Top Hypereutectic Pistons
These ruggedly durable pistons are made with exclusive high strength FM425 alloy, and enhanced with 16.5% silicon for excellent tensile strength and scuff resistance. This advanced metallurgy permits tighter bore clearances, which help minimize noise on cold engine start-up.
These pistons are the ideal choice for street performance applications and late-model replacement.
