CHEV/ HOLDEN LS2 PISTONS 4.040″ BORE, .945″ PIN, 1.325″

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
minimize 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
