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

File-fit means the end gap of the piston rings needs to be adjusted by the installer to match the specific cylinder bore of your engine. This ensures a proper seal and prevents the ring from binding as it expands with heat.

What materials are the JE Pistons ring set made from?

The top ring is carbon steel nitride, the second ring is ductile iron phosphate, and the oil ring is carbon steel chrome. These materials are chosen for their sealing capabilities, durability, and friction reduction.

Are these piston rings compatible with all engines?

These are universal piston rings offered in various sizes. While designed for high performance, you must ensure the dimensions and gap are correctly set for your specific engine application. They are not CARB approved and cannot ship to California.

Product Details

This is a JE Pistons ring set, part number JG7708-4120-5. These rings are designed to create a precise seal for combustion pressure, which helps maximize horsepower. They are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation. This set features a 0.043 inch carbon steel nitride top ring, a 0.043 inch ductile iron phosphate second ring, and a 0.1181 inch carbon steel chrome low tension oil ring.

JE Pistons offers these rings in a wide variety of sizes and materials to fit many different engines. The top ring is made from carbon steel with a nitride treatment for durability and sealing. The second ring is constructed from ductile iron with a phosphate coating, which also aids in sealing and wear resistance. The oil ring is a low-tension carbon steel design with a chrome face, intended to manage oil efficiently while minimizing drag.

These rings are the same type used by professional racing teams, and they can offer improved durability and reduced friction for better power output. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper gapping and fitting procedures.
