JE Pistons Ring Sets 1.2-1.2-3mm MOLY

Starting with a 0.0472 inch carbon steel plasma moly top ring, these JE Piston rings are built to seal combustion pressure effectively. This set is designed for 8-cylinder engines and includes a 0.0472 inch ductile iron phosphate second ring and a 0.1181 inch carbon steel chrome low tension oil ring. JE Pistons is well-known for their work with top racing teams, and the same precision sealing technology that helps maximize horsepower in Pro Stock and NASCAR is incorporated here. This means you get reduced friction and improved durability for your engine build.

These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation, a common practice for performance engine builds to ensure a perfect seal. The moly coating on the top ring is a popular choice for its ability to reduce friction and wear, contributing to longer engine life and consistent power output. While these are designed for a wide variety of engines, remember they are not CARB approved and cannot be shipped to California.
