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
