JE Piston Ring Set for four cylinders combines a plasma-moly ductile iron top ring, iron phosphate second ring and carbon steel chrome oil ring in a file-fit assembly. The construction aims to maximize sealing while minimizing drag. JE supports many ring sizes, material options and custom services—back cutting, lapping and PVD—used by pro teams to improve durability, friction and overall ring seal.
