Designed for select Honda TRX350 Rancher 4X4 models, this kit includes the essential components needed for a complete top-end rebuild: piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit. The piston features a 78.71 mm (+0.25 mm) oversize specification and an 11:1 compression ratio for compatible applications.\u003c\/p\u003e\u003cp\u003eNamura uses a hypereutectic casting process to increase silicon content, helping reduce expansion rates, improve wear resistance, and withstand elevated cylinder temperatures. The piston skirts feature a rolled-on MOS2 coating made from Teflon and molybdenum. This bonding process is designed to provide strong adhesion, improve heat transfer, reduce friction, and help minimize the risk of cold seizures during operation. Machined smooth heads help reflect combustion heat and reduce carbon buildup, while anodized domes improve heat resistance and durability.\u003c\/p\u003e\u003cp\u003eThis top-end kit is manufactured for fitment on 2000-2006 Honda TRX350FE Rancher 4X4 ES models and 2000-2002 Honda TRX350FM Rancher 4X4 models listed below.
