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
