JE Pistons Ring Sets .95-1.5-2.0-9900

The top ring on this JE Piston set is made from 0.0374-inch thick carbon steel with a nitride finish, designed to maximize horsepower by precisely sealing combustion pressure. This set includes a 0.0591-inch iron phosphate second ring and a 0.0787-inch low-tension carbon steel oil ring. JE Pistons offers these rings in a wide selection of sizes and materials, suitable for both street and racing applications. They also provide custom services like back cutting and PVD coating, similar to what top professional racing teams use, to further enhance durability and reduce friction for improved power and seal.

These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation. This allows for a more precise fit and better sealing compared to pre-gapped rings. While these are not CARB approved and cannot be shipped to California, they represent a well-built option for engine rebuilds where optimal sealing and performance are key.
