JE piston rings are available as single-cylinder file-fit sets for precise sealing in custom builds. This 1-cylinder kit uses a 0.0394" carbon steel nitride top ring, a 0.0472" ductile iron phosphate second ring and a 0.0787" carbon steel chrome low-tension oil ring. JE supports advanced finishing services—back cutting, lapping and PVD coating—to refine ring fit, reduce friction and improve long-term seal and durability.
