JE Pistons Ring Sets 1.2-1.5-3.0 RINGS

JE Pistons ring sets are built to help your engine make more power by ensuring a tight seal in the combustion chamber. This particular set, part number J75008-4080-5, is designed for 8-cylinder engines and features a file-fit design, meaning you'll need to gap the rings to your specific cylinder bore for optimal performance. The top ring is a 0.0472-inch thick 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 low tension type.

JE Pistons is known for working with top racing teams, and they bring that same level of precision to their aftermarket parts. These rings are constructed with durable materials like carbon steel and iron phosphate, chosen for their ability to withstand high temperatures and pressures while minimizing friction. The plasma moly top ring offers improved wear resistance, and the low-tension oil ring helps reduce drag for better efficiency. This combination is key to achieving a solid seal that maximizes horsepower and helps maintain engine health.

Because these are file-fit rings, they require careful measurement and gapping to match your engine's specific bore size. This ensures a perfect seal and is a common practice when rebuilding or modifying engines for improved performance. Please note that this part is not CARB approved and cannot be shipped to California.
