Part Number: SPH345DCP 020
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 minimise noise on cold engine start-up. These pistons are the ideal choice for street performance applications and late-model replacement.
More Sealed Power hypereutectics benefits:
Higher strength than cast or forged at operating temperature
Finely dispersed silicon particles provide a highly resistant wear surface and reduces scuffing
Lower material growth allows pistons to be fit tighter, improving cylinder sealing for less blow-by and more power
High silicon content allows elimination of groove inserts in certain applications
Designed to retain standard ring gaps in the top groove
