JE Pistons Ring Sets 1.2-1.2-3mm MOLY

The top ring on this JE Piston set features a 0.0472 inch thick plasma moly coating over carbon steel, a choice that matters for sealing combustion pressure effectively. This set is built for a single cylinder and is file-fit, meaning you'll adjust it to your specific cylinder bore during installation. The second ring is made from ductile iron phosphate at the same 0.0472 inch thickness, and the oil ring is a 0.1181 inch carbon steel chrome standard tension design.

JE Pistons designs these rings to help you get the most horsepower out of your engine by ensuring a tight seal. They offer a wide variety of sizes and materials to fit many different engines. The same custom services used by top racing teams, like back cutting and PVD coating, are available to improve durability, reduce friction for more power, and enhance the ring seal.
