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
