JE Pistons Ring Sets 1.2-1.2-3mm MOLY

JE Pistons is a well-known name in performance engine building, and they bring that expertise to their piston ring sets. This particular set, part number J92601-4070-5, is designed to create a tight seal in your cylinder, which is crucial for maximizing horsepower by effectively containing combustion pressure. They offer these rings in a wide variety of sizes and materials to fit many different engines.

This set features a 0.0472-inch thick carbon steel plasma moly top ring, a 0.0472-inch ductile iron phosphate second ring, and a 0.1181-inch carbon steel chrome low-tension oil ring. These are file-fit rings, meaning you'll need to gap them to your specific cylinder bore for optimal performance and sealing. The same advanced services JE offers to top racing teams, like PVD coating for reduced friction and improved durability, are available to the public, though this specific set does not include those custom options.
