JE Pistons Ring Sets 1.2-1.5-3.0 RINGS

JE Pistons ring sets are built for engines needing a precise seal to get the most out of combustion pressure. This particular set, part number J750F8-4060-5, is designed for 8-cylinder applications and features a file-fit design, meaning you can fine-tune the end gap for your specific build. The top ring is a 0.0472-inch carbon steel plasma moly, the second ring is a 0.0591-inch iron phosphate, and the oil ring is a 0.1181-inch carbon steel chrome standard tension ring.

These rings are constructed with durable materials like carbon steel and iron phosphate, chosen for their ability to create a solid seal under high heat and pressure. The plasma moly top ring offers improved wear resistance, while the iron phosphate second ring helps control blow-by. The standard tension chrome oil ring is well-suited for managing oil consumption. JE Pistons uses the same ring services, like back cutting and PVD coating, for top racing teams, which can lead to significant gains in durability and reduced friction for better power.

Because these are file-fit rings, they require careful measurement and adjustment of the end gap to ensure proper fitment and sealing in your engine cylinders. This level of customization allows for optimal performance in a wide variety of engines, especially those built for higher horsepower output. Please note that this part is not CARB approved and cannot be shipped to California.
