Description

Available on both
hypereutectic and POWERFORGED
pistons, DUROSHIELD is an
exclusive moly-graphite skirt

coating that extends
engine life and essentially
eliminates scuffing. This
technologically advanced
coating is precisely applied
to the piston through a
computer-controlled process.

DUROSHIELD
skirt coated pistons:

• Reduce friction
  for increased fuel economy
  and horsepower
• Essentially eliminate
  scuffing and wear
• Prevent damage from
  inadequate lubrication,
  especially at start-up
• Improve cylinder sealing
  for less blow-by and more
  power
• Require no
  increase in skirt clearance
