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

File-fit means the end gaps of the piston rings are not pre-set. You will need to measure the cylinder bore and carefully file the ring ends to achieve the correct gap before installing them. This allows for a custom fit to your specific engine build.

What materials are the rings made from?

The top ring is made of ductile iron with a plasma moly coating, the second ring is iron phosphate, and the oil ring is carbon steel with a low-tension design.

Are these rings CARB approved?

No, these rings are not CARB approved and cannot be shipped to California.

Product Details

When you're rebuilding the top end of your engine, getting the piston rings seated correctly is crucial for sealing combustion pressure and maximizing horsepower. These file-fit piston ring sets from JE Pistons are designed for just that purpose. They offer a way to achieve precise sealing, which is essential for getting the most out of your engine build.

This particular set features a 1/16-inch ductile iron plasma moly top ring, a 1/16-inch iron phosphate second ring, and a 3/16-inch carbon steel low-tension oil ring. The file-fit design means you can custom-size the end gaps for your specific cylinder bore, ensuring a perfect seal. JE Pistons uses the same ring technology that top racing teams rely on, which can lead to improved durability and reduced friction.

Remember that these rings are file-fit, so you'll need to carefully measure and file the end gaps to match your cylinder bore before installation. Refer to the manufacturer's installation instructions for the proper procedure.
