JE Pistons Ring Sets 1.0-1.2-2.8-3.307

Starting with a 0.0394-inch thick carbon steel nitride top ring, this JE Pistons ring set is built for serious sealing. That precision is carried through with a 0.0472-inch ductile iron phosphate second ring and a low-tension, 0.1102-inch carbon steel nitride oil ring. These components work together to maximize horsepower by ensuring a tight seal against the cylinder wall, preventing combustion pressure from escaping and maintaining consistent oil control. JE Pistons offers these sets in a wide variety of sizes and materials to fit many different engines, and they use the same techniques trusted by top racing teams to improve durability and reduce friction.

This particular set, part number JG1006-3307, is designed for 6-cylinder engines and features file-fit rings, meaning you'll need to gap them to your specific cylinder bore for optimal performance. The combination of carbon steel nitride and ductile iron materials offers a solid balance of strength and sealing capability. While these rings are not CARB approved and cannot be shipped to California, they represent a well-built option for engine rebuilds where precise sealing and improved power are key goals.
