JE Pistons Ring Sets 1.2-1.2-3mm MOLY

When you're rebuilding the top end of your engine, getting the piston rings seated properly is crucial for sealing combustion pressure. This set from JE Pistons is designed to help you achieve that seal, which is key to maximizing horsepower and ensuring your engine runs smoothly. They use a common 1.2-1.2-3mm size combination, making them suitable for a wide range of engine builds.

This particular set features a file-fit top ring made of carbon steel with a plasma moly coating, which helps reduce friction and improve durability. The second ring is ductile iron with a phosphate coating, and the oil ring is standard tension carbon steel with chrome. File-fit rings allow you to precisely adjust the end gap for your specific cylinder bore, ensuring a tight seal. JE Pistons is known for supplying top racing teams, and these rings reflect that level of attention to detail.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitting and installation procedures to get the best performance from your new rings.
