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

File-fit rings require you to carefully file the end gap to the correct specification for your cylinder bore. This allows for a precise fit, which is important for optimal sealing and performance in your engine.

What is the advantage of the plasma moly coating on the top ring?

The plasma moly coating on the top ring helps to reduce friction and improve wear resistance. This contributes to better sealing of combustion pressure, which can lead to increased horsepower and engine durability.

Are these rings compatible with all engine builds?

This set is designed for 8-cylinder engines and features file-fit rings, which require specific installation procedures. While they offer excellent sealing, it's important to ensure they are suitable for your particular engine build and that installation is performed correctly.

Product Details

The top ring on this JE Pistons set is made from 0.064 inch ductile iron with a plasma moly coating, a strong choice for sealing combustion pressure and maximizing horsepower. This set is designed for 8-cylinder engines and features file-fit rings, meaning you can precisely adjust the end gap to match your specific cylinder bore for optimal performance. The second ring is also 0.064 inch, constructed from iron phosphate for durability, while the oil ring is a low-tension 0.188 inch carbon steel chrome design.

JE Pistons is well-known for the same ring services used by top racing teams, offering custom options like back cutting and PVD coating for even greater durability and reduced friction. This particular set is built to provide a solid seal, which is crucial for consistent engine power and longevity. Because these are file-fit rings, you'll want to ensure you have the proper tools and knowledge for installation, or consult a professional mechanic to get the end gap just right for your engine build.

This ring set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and setup.
