What does 'file fit' mean for these piston rings?

File fit means the ends of the piston rings are not pre-gapped. You will need to measure your cylinder bore and carefully file the ring ends to achieve the correct gap before installing them. This allows for a custom fit to your engine's specific bore size.

What materials are the JE Pistons XC9050 rings made from?

The top ring is made of carbon steel with a chrome face, and the oil ring is also carbon steel with a chrome face. The second ring is made of iron phosphate. This combination is chosen for durability and sealing performance.

Are these piston rings CARB approved?

No, these piston rings are not CARB approved and cannot be shipped to California. Please check local regulations regarding emissions compliance for engine components.

Product Details

This is a JE Pistons piston ring set, part number XC9050. These rings are designed to seal combustion pressure effectively, which helps maximize horsepower. They are a file-fit style, meaning you'll need to gap them to your specific cylinder bore during installation. The set includes a 0.0394-inch carbon steel chrome top ring, a 0.0472-inch iron phosphate second ring, and a 0.1102-inch low tension carbon steel chrome oil ring.

JE Pistons uses the same ring technology that top racing teams in NHRA Pro Stock and NASCAR rely on. This means you're getting well-built components that can offer improved durability and power by reducing friction and ensuring a solid seal. Because these are file-fit, they offer a unique ability to be precisely gapped for your engine's specific bore size, which is crucial for optimal performance in a rebuild.

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