JE piston ring set delivers precision sealing of combustion pressure to help maximize horsepower and reduce blow-by. Offered in a wide range of sizes, materials and thicknesses, each one-cylinder file-fit set pairs a carbon steel chrome top ring, an iron-phosphate second ring and a low-tension carbon steel chrome oil ring with a stainless-steel spacer oil assembly. JE also provides custom services—back cutting, dyke cutting, lapping, grinding and PVD coating—used by NHRA Pro Stock and NASCAR teams to reduce friction, boost durability and improve ring seal for street and racing builds.
