This JE Pistons single-cylinder file-fit ring set uses a plasmy-moly ductile iron top ring, an iron-phosphate second ring and a carbon steel chrome oil ring in the specified thicknesses to provide strong sealing for high-output engines. JE emphasizes precision sealing to maximize horsepower, and offers custom ring work—back cutting, lapping, dyke cutting and PVD coating—used by pro teams to increase durability and reduce internal friction.
