JE Pistons Ring Sets 1.0-1.2-2.8-3.622

JE Pistons is a well-known name for high-performance engine components, and these piston ring sets carry on that reputation. They are built to maximize horsepower by ensuring a tight seal for combustion pressure. You can find them in a wide variety of sizes and thicknesses to match many different engines. This particular set is designed for a 1-cylinder application and features file-fit top rings, meaning you can adjust them to your specific cylinder bore for a perfect seal. The top ring is 0.0394 inches thick, made of carbon steel with a nitride finish for durability. The second ring is 0.0472 inches thick and made of ductile iron with a phosphate coating. For the oil ring, you get a low-tension 0.1102-inch carbon steel nitride ring, which helps reduce friction while still controlling oil.

These are the same types of services and components used by top racing teams, offering gains in durability and power through reduced friction and an improved ring seal. Keep in mind that these rings are not CARB approved and cannot be shipped to California.
