Description
Overview:
This Replacement Piston is a genuine Honda component for GX120K1 (GC01) and GX120U1 small petrol engines. Manufactured to Honda OEM standards, the piston restores correct compression and smooth running when the original part has worn or been damaged. The body is precision‐made from durable aluminium alloy to balance low weight with strength and effective heat dissipation in continuous service. It is designed as a direct replacement within the GX120 top end, working with the matching cylinder, rings, gudgeon pin, and connecting rod specified for these engines. Commonly found on equipment such as generators, water pumps, pressure washers, and compactors, the GX120 platform benefits from timely piston renewal to maintain reliable starting, stable idle, and consistent power output. Genuine Honda part number: 13101-ZH7-010.
