JE Pistons Ring Sets 1.2-1.5-3.0-102.67

JE Pistons is well-known for making high-performance engine components, and this piston ring set is built to that standard. These rings are designed to seal combustion pressure effectively, which helps maximize horsepower. They are a file-fit set, meaning you'll need to gap them to your specific application, a common practice for performance builds where precise control over ring seal is important.

This set features a 0.0472-inch carbon steel nitride top ring, a 0.0591-inch iron phosphate second ring, and a 0.1181-inch carbon steel chrome standard tension oil ring. The combination of materials and thicknesses is chosen to provide a strong seal. JE Pistons offers custom services like back cutting and PVD coating, used by top racing teams, which can further improve durability and reduce friction for even better power gains and ring seal, though these specific rings are sold as-is.

Because these are file-fit rings, they require careful installation and gapping to ensure proper fitment and performance in your engine. Please note that this set is not CARB approved and cannot be shipped to California.
