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.

• 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
