JE Pistons Ring Sets 1.2-1.2-3.0-86.00

The top ring on this JE Piston ring set is made from carbon steel with a chrome finish, measuring 0.0472 inches thick. This material and thickness are chosen to create a strong seal against the cylinder wall, which is crucial for maximizing horsepower by preventing combustion pressure from escaping. The second ring is also 0.0472 inches thick, made from iron ferroxide, and works in conjunction with the top ring to further enhance sealing. For the oil ring, you get a 0.1181-inch thick carbon steel ring with a chrome finish, designed for low tension to effectively scrape oil from the cylinder walls without creating excessive drag.

These rings are file-fit, meaning you'll need to gap them yourself to perfectly match your cylinder bore. This level of customization is what top racing teams use to achieve the best possible seal and reduce friction, leading to gains in both durability and power. JE Pistons offers these same advanced services to the public, ensuring you get a well-built set that can handle demanding applications.

Please note that this ring set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper gapping and fitting procedures.
