JE Pistons Ring Sets 1.0-1.2-2.8-3.484

JE Pistons Ring Sets JG1001-3484 are built to help your engine make the most power by ensuring a tight seal for combustion pressure. This particular set is designed for a 1-cylinder application and features a file-fit design, meaning you can fine-tune the end gap to your specific cylinder bore for optimal performance. The top ring is a 0.0394-inch thick carbon steel nitride ring, known for its strength and ability to handle high temperatures. The second ring is a 0.0472-inch ductile iron phosphate ring, which works with the top ring to maintain a solid seal.

The oil control ring in this set is a low-tension 0.1102-inch carbon steel nitride ring. Low tension means it exerts less pressure on the cylinder wall, which can reduce friction and improve engine efficiency. JE Pistons uses the same ring technology that top racing teams rely on, offering gains in durability and power. This set is a well-built option for engine rebuilds where precise sealing is critical.
