The kit includes the piston, piston rings, wrist pin, circlips, top-end bearing, and gasket kit for a complete upper-engine rebuild solution.\u003c\/p\u003e\u003cp\u003eThe NAMURA piston uses a hypereutectic casting process with increased silicon content to help reduce expansion, improve wear resistance, and withstand elevated cylinder temperatures. Its MOS2 Teflon\/molybdenum-coated skirts are applied through a rolled-on process that creates a durable bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizure. The machined smooth head helps reflect combustion heat and limit carbon buildup, while the anodized dome improves heat resistance and durability.\u003c\/p\u003e\u003cp\u003eManufacturer: NAMURA.
