Description
Overview:
This piston ring set is a genuine Honda replacement for selected GX-series single-cylinder engines, including GX340T2 and GX390T1. Manufactured to Honda's specification from high-quality, wear-resistant steel, the rings restore correct sealing in the combustion chamber, maintain compression, and control oil on the cylinder wall. This helps the engine start reliably, run smoothly, and use fuel efficiently. Designed for construction and garden machinery powered by Honda industrial engines, it is suitable for equipment such as generators, pumps, compactors, and large mowers. As an OEM component (OEM No. 13013 Z5R 004), it offers an accurate fit and dependable performance without modification. Branded Honda and supplied as a matched set, it is ideal for routine overhaul and corrective maintenance.
