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

JE Pistons is a well-known name in high-performance engine components, trusted by top racing teams for their commitment to precision and power. This particular ring set, the 1.2-1/16-3mm GOLDCUP, is built to help your engine breathe easier and make more power by ensuring a tight seal in the combustion chamber. Whether you're rebuilding a classic V8 or working on a custom project, getting the right piston rings is crucial for performance and longevity.

This set is designed for 8-cylinder engines and features a file-fit design, meaning you can precisely tailor the end gap to your specific cylinder bore for optimal sealing. The top ring is made from stainless steel with a titanium nitride coating, offering excellent durability and resistance to blow-by. Beneath that, you'll find a 0.064-inch iron phosphate second ring, and the oil control ring is a 0.1181-inch carbon steel with a chrome finish and low tension design to manage oil effectively without creating excessive drag. These materials and dimensions are chosen to maximize horsepower by precisely sealing combustion pressure and reducing friction.

JE Pistons offers custom services like back cutting and PVD coating, similar to what they provide to NHRA Pro Stock and NASCAR teams, which can further enhance durability and power. While this specific set is not CARB approved and cannot be shipped to California, it represents a solid option for engine builders looking for improved ring seal and reduced friction. Remember to consult your engine's service manual for proper installation procedures and ring gap specifications.
