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 size of your engine. This ensures proper sealing and prevents the ring from butting up against itself as it expands with heat.

What materials are these piston rings made from?

The top and oil rings are made from carbon steel with a chrome finish, while the second ring is made from iron phosphate. This combination is chosen for durability and effective sealing.

Are these rings compatible with all JE Pistons?

These rings are designed to work with JE pistons, but it's always best to verify compatibility with your specific JE piston part number and engine build to ensure the correct dimensions and application.

Product Details

When you're rebuilding the top end of your engine, getting the piston rings seated correctly is crucial for performance and longevity. These JE Pistons ring sets are built to seal combustion pressure effectively, which directly translates to more horsepower and a healthier engine. They're designed to work with JE pistons, ensuring a solid fit and function for your build.

This particular set features a 0.0472-inch thick carbon steel chrome top ring and a matching 0.0472-inch iron phosphate second ring. For the oil control, it includes a 0.1181-inch low-tension carbon steel chrome oil ring. These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore for optimal performance. The carbon steel chrome construction on the top and oil rings offers good durability and sealing, while the iron phosphate second ring helps manage oil consumption.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper gapping and seating procedures.
