JE Pistons Ring Sets 1.2-1.2-3mm RING SET

JE Pistons is a well-known name in high-performance engine building, often chosen by top racing teams. This specific piston ring set is designed to maximize horsepower by ensuring a precise seal for combustion pressure. It features a 0.0472-inch carbon steel nitride top ring, a 0.0472-inch ductile iron phosphate second ring, and a 0.1181-inch carbon steel chrome standard tension oil ring.

These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation, a common practice for performance builds to achieve optimal sealing. The combination of materials, including nitride and phosphate coatings on the top and second rings respectively, along with a chrome-plated oil ring, is chosen to balance durability and reduced friction for improved power output. JE Pistons offers custom services like back cutting and PVD coating, which are the same techniques used by professional racers to further enhance durability and power.

This set is intended for 8-cylinder engines. Please note that this part is not CARB approved and cannot be shipped to California.
