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

File-fit rings are not pre-gapped to a specific size. You will need to measure your cylinder bore and carefully file the ends of the rings to achieve the correct gap before installation. This allows for a precise fit in custom or non-standard bore sizes.

What materials are used in this piston ring set?

The top and second rings are made from ductile iron, with the top ring featuring a plasma moly coating and the second ring a phosphate coating. The oil ring is constructed from carbon steel with a chrome plating and a low-tension design.

Are these piston rings CARB approved?

No, these piston rings are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Starting with a 0.064 inch ductile iron plasma moly top ring, these JE Piston rings are built to seal combustion pressure effectively. This set includes a matching 0.064 inch ductile iron phosphate second ring and a 0.188 inch carbon steel chrome low tension oil ring, all designed for a single cylinder application. JE Pistons offers these rings in a wide selection of sizes and materials to fit many different engines.

The construction here aims to maximize horsepower by ensuring a tight seal within the cylinder. The combination of ductile iron for the top and second rings, along with carbon steel for the oil ring, balances sealing performance with reduced friction. This attention to detail is the same approach used by professional racing teams, aiming for improved durability and power.

This ring set is file-fit, meaning you'll need to gap the rings to your specific cylinder bore during installation. Always refer to the manufacturer's installation instructions for proper gapping and fitting procedures.
