JE Pistons Ring Sets 1.0-1.2-2.8-2.638

This piston ring set features a 0.0394-inch thick carbon steel chrome top ring, designed to precisely seal combustion pressure and help maximize horsepower. The second ring is 0.0472 inches thick and made from iron phosphate, while the oil ring is a low-tension 0.1102-inch carbon steel chrome design. JE Pistons offers these rings in a wide selection of sizes and materials to fit many different engines, from street use to racing applications. They also provide custom services like back cutting and PVD coating, similar to what top professional racing teams use, which can improve durability and reduce friction for better power output.

These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation. This allows for a more precise fit, which is crucial for optimal sealing and performance. While these rings are not CARB approved and cannot be shipped to California, they represent a well-built option for engine rebuilds where precise sealing is a priority.
