JE Pistons Ring Sets .043-.043-3.0-115.189

When you're rebuilding the top end of your engine, getting the piston rings seated just right is critical for sealing combustion pressure. This set from JE Pistons is designed to help you achieve that seal, maximizing the horsepower your engine can make. They offer a huge selection of sizes and materials, and this particular set is built for 8-cylinder applications.

This ring set features file-fit top rings, meaning you can fine-tune the gap for your specific cylinder bore, which is a common practice for performance builds. The top ring is made from carbon steel with a nitride finish for durability, while the second ring is ductile iron with a phosphate coating. For the oil ring, you get a low-tension carbon steel chrome design. These are the same types of services and materials used by top racing teams, offering gains in durability and reduced friction for better power.

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 fitting procedures.
