This JE Pistons eight-cylinder file-fit ring set includes a 0.064" hard ductile iron phosphate top ring, a 0.064" iron phosphate second ring, and a 0.188" carbon steel chrome standard tension oil ring, aimed at restoring compression seal and consistent oil control across a full engine. JE supports numerous sizes, materials and precision services—back cutting, dyke cutting, lapping and coating—used to improve ring seal and reduce friction in boosted or high-RPM builds.
