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

File-fit means the ends of the piston rings are not pre-gapped. You will need to carefully measure and file the ends of the rings to achieve the correct gap for your specific cylinder bore size. This allows for a more precise fit in performance applications.

What are the ring thicknesses in this set?

This set features a 0.0472-inch thickness for both the top and second rings, and a 0.1102-inch thickness for the low-tension oil ring.

Are these rings suitable for all engine types?

JE Pistons offers a wide selection of ring sizes and thicknesses to suit various engines. While this set is designed for performance sealing, it's important to verify that the specific dimensions and type match your engine's requirements.

Product Details

When you're rebuilding the top end of your engine, getting the piston rings seated just right is critical for sealing combustion pressure and making good power. These file-fit piston ring sets from JE Pistons are built to help you achieve that precise seal. They come in a variety of sizes and thicknesses to match different engine builds.

This particular set includes a 0.0472-inch thick carbon steel chrome top ring, a 0.0472-inch iron phosphate second ring, and a 0.1102-inch low-tension carbon steel chrome oil ring. The file-fit design means you'll need to gap these rings yourself to perfectly match your cylinder bore, a common practice for performance builds to ensure optimal sealing and prevent blow-by. JE Pistons uses the same techniques for these rings as top racing teams, aiming for reduced friction and improved durability.

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.
