JE Pistons Ring Sets 1.2-1.5-2mm-3.858

This JE Pistons ring set includes a file-fit top ring made of carbon steel with a chrome finish, an iron phosphate second ring, and a low-tension oil ring also in carbon steel with a chrome finish. These rings are designed to create a precise seal for combustion pressure, which helps maximize horsepower. They are offered in a variety of sizes and thicknesses to fit many different engines, and JE Pistons also offers custom services like back cutting and PVD coating for even more durability and reduced friction.

The top ring is 0.0472 inches thick, the second ring is 0.0591 inches thick, and the oil ring is 0.0787 inches thick, with a bore size of 3.858 inches. These are file-fit rings, meaning you'll need to carefully file the ends to achieve the correct gap for your specific cylinder bore. This ensures a tight seal and prevents blow-by, which is crucial for engine performance.
