JE Pistons Ring Sets 1.2-1/16-3mm GOLDCUP

When you're rebuilding the top end of your engine and need reliable sealing for peak performance, a quality set of piston rings is crucial. These JE Pistons GOLDCUP ring sets are designed to precisely seal combustion pressure, which is key to maximizing horsepower. They come in a variety of sizes and thicknesses to fit many different engines, and JE Pistons has a long history of supplying top racing teams with their ring technology.

This particular set features a 0.0472-inch thick stainless steel top ring with a titanium nitride coating for improved durability and sealing. The second ring is 0.064 inches thick and has an iron phosphate finish, which helps with initial break-in and oil control. For the oil control ring, you get a 0.1181-inch carbon steel chrome low-tension ring. These materials and thicknesses are chosen to work together for a strong seal and reduced friction, contributing to both power gains and improved durability. JE Pistons also offers custom services like back cutting and PVD coating, similar to what you'd find on rings used by professional NHRA and NASCAR teams, to further enhance performance and longevity.

It's important to note that these rings are file-fit, meaning you'll need to gap them to your specific cylinder bore dimensions during installation. This allows for a precise fit and optimal performance. Also, be aware 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.
