JE Pistons Ring Sets 1/16-1/16-3mm RING

The top ring in this JE Pistons set is made from ductile iron with a plasma moly coating, measuring 1/16 inch thick. This material and coating choice is key for creating a strong seal against the cylinder wall, which helps maximize combustion pressure and, in turn, horsepower. The second ring is also 1/16 inch and features an iron phosphate finish, further contributing to a solid seal and durability.

Completing the set is a 0.1181 inch (or 3mm) low-tension oil ring made from carbon steel with a chrome finish. Low-tension oil rings are designed to reduce drag on the cylinder wall, which can lead to improved engine efficiency and reduced friction. This combination of materials and precise dimensions is what JE Pistons uses for top racing teams, aiming for improved durability and power.

This ring set is designed for 8-cylinder engines and is file-fit, meaning you'll need to gap the rings to your specific cylinder bore during installation. Because these are file-fit, they offer a lot of flexibility for custom builds or when working with non-standard bore sizes. Remember that this set is not CARB approved and cannot be shipped to California.
