This kit includes a 93.46 mm (+1.50 mm) piston with an 11:1 compression ratio, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit. It provides the essential components needed for a dependable piston and cylinder service while supporting proper engine performance and durability.\u003c\/p\u003e\u003cp\u003eThe piston uses a hypereutectic casting process that increases silicon content to help reduce expansion and improve wear resistance. Its MOS2, or Teflon\/molybdenum, coated skirts are applied using a rolled-on process that creates a stronger bond than conventional spray-on coatings. This coating helps promote heat transfer, reduce friction, and minimize the risk of cold seizures. The machined smooth head helps reflect combustion heat and reduce carbon buildup, while the anodized dome improves heat resistance and durability.\u003c\/p\u003e\u003cp\u003eFeature: Complete top-end kit with piston, rings, wrist pin, clips, top-end bearing, and gasket kit\u003cbr\u003eFeature: 93.46 mm (+1.50 mm) piston size with an 11:1 compression ratio\u003cbr\u003eFeature: MOS2-coated piston skirts for reduced friction and improved protection during cold operation\u003cbr\u003eFeature: Machined smooth piston head helps reduce carbon buildup and reflect combustion heat\u003cbr\u003eFeature: Anodized piston dome for increased heat resistance and durability\u003cbr\u003eFeature: Hypereutectic construction supports reduced expansion and improved wear resistance\u003c\/p\u003e\u003cp\u003eManufacturer: NAMURA.
