JE Pistons Ring Sets 1.2-1.5-3.0-105.61

JE Pistons is well-known for making high-performance engine components, and this piston ring set is a great example of their work. These rings are built to maximize horsepower by precisely sealing combustion pressure. They are designed for an 8-cylinder engine and come in a 105.61mm bore size, with specific ring thicknesses: a 0.0472-inch carbon steel nitride top ring, a 0.0591-inch iron phosphate second ring, and a 0.1181-inch carbon steel chrome standard tension oil ring.

This set is file-fit, meaning you'll need to gap the rings to your specific cylinder bore for optimal performance and sealing. This approach is common in performance builds and allows for a more tailored fit. JE Pistons offers custom services like back cutting and PVD coating, used by top racing teams, which can further improve durability and reduce friction for even better power gains and ring seal.

This particular 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.
