JE Pistons Ring Sets 1.0-1.2-2.8-3.524

JE Pistons has a reputation for making high-performance engine parts. This piston ring set is built to seal combustion pressure effectively, which helps maximize horsepower. They offer these rings in a wide range of sizes and materials to fit many different engines. The top ring is made from carbon steel with a nitride finish, measuring 0.0394 inches thick. The second ring is ductile iron with a phosphate finish, at 0.0472 inches thick. For the oil ring, it's a low-tension carbon steel nitride design that's 0.1102 inches thick.

These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation. This is a common practice for performance builds, allowing for precise control over the ring seal. The same advanced services used by top racing teams, like back cutting and PVD coating, are available from JE Pistons, which can lead to improved durability and reduced friction for even more power.
