JE Pistons Ring Sets .043-.043-3.0-103.251

This is a JE Pistons piston ring set, part number JG7708-4060-5. These rings are built for 8-cylinder engines and are designed to seal combustion pressure effectively, which helps maximize horsepower. They are file-fit, meaning you'll need to gap them to your specific application during installation, a common practice for performance builds. The set includes a 0.043 inch carbon steel nitride top ring, a 0.043 inch ductile iron phosphate second ring, and a 0.1181 inch carbon steel chrome low tension oil ring.

JE Pistons offers these rings in a wide variety of sizes and materials to fit many different engines. The specific construction here uses carbon steel for the top ring, known for its strength and ability to handle high temperatures, treated with a nitride coating for improved durability. The second ring is made from ductile iron, which offers good sealing properties, and is phosphate coated. For the oil control, a low tension carbon steel chrome ring is used to manage oil while minimizing drag. These are the same types of rings used by professional racing teams, indicating a focus on performance and durability.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Proper gapping during installation is crucial for optimal performance and engine longevity.
