HARD ANODIZED CROWNS - STRONGER SURFACE: 75% stronger than non-anodized. Heat resistant with minimal expansion/contraction
MOS2 SKIRTS Teflon/Molybdenum blended coating. Non-abrasive, proven to have very high durability
SILICON CONTENT - HYPEREUTECTIC CAST Increases hardness of the aluminum. More resistant to wear and scuffing, less heat expansion and tighter clearances
