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

File-fit means the end gaps of the piston rings are not pre-set. You will need to file them to the correct size for your specific cylinder bore before installation. This allows for a more precise seal tailored to your engine.

What materials are these piston rings made from?

The top ring is made from ductile iron with a Plasmy Moly coating, the second ring is iron phosphate, and the oil ring is carbon steel with chrome plating. These materials are chosen for durability and sealing performance.

Are these rings suitable for all engine builds?

These rings are designed for engine builds where precise sealing is important for horsepower. However, they are not CARB approved and cannot be shipped to California. Always confirm compatibility with your specific engine build requirements.

Product Details

When you're rebuilding the top end of your engine, getting the right piston rings is crucial for sealing combustion pressure and making sure everything runs smoothly. These file-fit rings from JE Pistons are designed to help you achieve that precise seal, which is key to maximizing horsepower. They come in a common size combination: a .043 inch ductile iron Plasmy Moly top ring, a .064 inch iron phosphate second ring, and a .188 inch carbon steel chrome oil ring.

JE Pistons is known for working with top racing teams, and they offer the same kind of custom services to the public, which means these rings are built with that level of attention to detail. The file-fit design means you'll need to gap them yourself to perfectly match your cylinder bore, ensuring a tight seal. This set uses a ductile iron top ring for good wear resistance and an iron phosphate second ring, paired with a carbon steel oil ring for effective oil control.

Remember, these rings are not CARB approved and cannot be shipped to California. Make sure to check the manufacturer's instructions for proper installation and gapping.
