JE Pistons Ring Sets 1.2-1.5-3.0-3.642

JE Pistons Ring Sets are built to help your engine seal combustion pressure effectively, which is key to making good horsepower. This particular set, part number JC2404-3642, is designed for 4-cylinder engines and features a specific ring sizing: 1.2mm for the top ring, 1.5mm for the second ring, and 3.0mm for the oil ring, with a bore size of 3.642 inches. The top ring is made from carbon steel with a chrome finish, while the second ring uses iron phosphate. The oil ring is a low-tension carbon steel chrome design.

These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation, a common practice for performance builds to ensure a perfect seal. JE Pistons uses the same ring services, like back cutting and PVD coating, that are trusted by top racing teams in NHRA Pro Stock and NASCAR. This means you're getting a well-built set that can offer gains in durability and reduced friction for improved power.

Keep in mind that this ring set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper gapping and fitting procedures.
