JE Pistons Ring Sets 1.5-1.5-4mm-3.327

The top ring on this JE Piston Ring set is made from 0.0591-inch thick ductile iron with a plasma moly coating, a solid choice for sealing combustion pressure effectively. This set includes a 0.0591-inch iron phosphate second ring and a 0.1575-inch carbon steel chrome standard tension oil ring, all designed to work together for optimal engine performance. JE Pistons offers these rings in a wide variety of sizes and materials, and they even provide custom services like back cutting and PVD coating, similar to what top racing teams use, to improve durability and reduce friction.

These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation, which is a common practice for performance builds to ensure a perfect seal. This attention to detail in design and the ability to customize them helps achieve better power and a more reliable seal within the combustion chamber.
