JE Pistons Ring Sets 1.2-1.2-2.0-86.50 PVD RS

The top ring on these JE Piston Rings is made from carbon steel with a PVD coating, measuring 0.0472 inches thick. This advanced coating helps reduce friction and improve durability, which is crucial for maximizing horsepower by ensuring a tight seal on combustion pressure. The second ring is also carbon steel at the same thickness, while the oil ring is a low-tension carbon steel nitride design at 0.0787 inches, all designed to work together for optimal engine performance.

JE Pistons offers these rings in a wide range of sizes and thicknesses to fit many different engines, and they use the same techniques trusted by top racing teams. The PVD coating, in particular, is a notable feature that contributes to significant gains in both power and longevity. These are file-fit rings, meaning they require careful fitting to your specific pistons during installation to achieve the best possible seal.

Because these rings are file-fit and designed for performance, they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitting and assembly to ensure you get the most out of this well-built set.
