The JE piston ring set for eight-cylinder engines is built for precise combustion sealing to support horsepower and reduce friction. This file-fit assembly features a 0.078" iron moly-fill top ring, a 0.078" iron phosphate second ring and a 0.188" carbon steel chrome low-tension oil ring, with a barrel-faced profile for low friction and a hard, wear-resistant surface. JE also offers custom ring services—back cutting, lapping, grinding and PVD coating—for specialized needs.
