JE Pistons Ring Sets 1.2-1.5-3.0 RINGS

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 J750F8-4135-5, is designed for 8-cylinder engines and features a specific ring thickness combination: a 0.0472-inch carbon steel plasma moly top ring, a 0.0591-inch iron phosphate second ring, and a 0.1181-inch carbon steel chrome standard tension oil ring.

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 the best possible seal. The top ring uses a plasma moly coating for improved durability and reduced friction, while the oil ring is standard tension chrome steel, designed for reliable oil control. JE Pistons is known for supplying top racing teams, and the same attention to detail goes into these sets, aiming for improved durability and power through better sealing and reduced friction.

Keep in mind that this 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.
