JE Pistons Ring Sets 1.0-1.2-2.8-3.287

This JE Pistons ring set includes a top ring, second ring, and oil ring, all designed for 6-cylinder engines. The top ring is made from carbon steel with a nitride coating, measuring 0.0394 inches thick. The second ring is ductile iron with a phosphate coating, at 0.0472 inches thick. The low-tension oil ring is also carbon steel with a nitride coating and is 0.1102 inches thick. These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore for optimal performance.

JE Pistons are well-known for their precision sealing capabilities, which helps maximize horsepower by keeping combustion pressure where it belongs. The combination of materials and coatings on these rings is chosen to reduce friction and improve durability. While these are file-fit rings, requiring careful installation to set the correct end gap, they are the same type of components used by top racing teams, indicating their robust design and performance potential.

Keep in mind that this set is 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 the best results for your engine rebuild.
