Piston:

MOS2 (Teflon/Molybdenum) Coated Skirts: A rolled on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures.

Gaskets:

Namura gaskets are manufactured to OE-specs, which means no trimming or fitment issues. Our materials are explicitly selected for their temperature, oil, fuel, and coolant-resistant qualities as well as tested using ASTM standards. Each design is evaluated against rigid quality-control standards to ensure each set meets or exceeds OE performance. Clutch gaskets are available for certain applications.
