JE Pistons Ring Sets 1.2-1.5-3.0-104.775

The top ring on these JE Piston rings is made from carbon steel and nitride treated, measuring 0.0472 inches thick. This construction is key to sealing combustion pressure effectively, which directly impacts how much horsepower your engine can make. JE Pistons offers these rings in a wide variety of sizes and thicknesses to fit many different engines, and they use the same techniques that top racing teams rely on for improved durability and reduced friction.

The second ring is 0.0591 inches thick and made from iron phosphate, while the standard tension oil ring is 0.1181 inches thick and also carbon steel, but with a chrome finish. This combination of materials and thicknesses is designed to work together for a solid seal. While these are file-fit rings, meaning they may require some adjustment to the end gap for your specific application, they are a popular choice for builders looking to get the most out of their engine rebuilds.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper gapping and fitting procedures to ensure optimal performance and longevity.
