Description
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
