JE Pistons Ring Sets 5/64-5/64-3/16 RING

When you're rebuilding the top end of your engine, getting the piston rings seated correctly is crucial for performance and longevity. These JE Pistons ring sets are built to ensure a tight seal against the cylinder wall, which is key to maximizing horsepower by keeping combustion pressure where it belongs. They come in a wide variety of sizes and thicknesses, so you can find the right fit for many different engines.

This particular set is designed for 8-cylinder engines and features file-fit rings, meaning you'll need to gap them to your specific cylinder bore for optimal performance. The top ring is made from ductile iron with a plasma moly coating for good sealing and durability, while the second ring is iron phosphate. The oil ring is a standard tension carbon steel with chrome, designed to manage oil effectively. JE Pistons uses the same techniques for these rings that top racing teams rely on, aiming for improved durability and reduced friction.

Because these are file-fit rings, they require careful measurement and gapping to match your engine's bore size. It's important to consult your engine's service manual for the correct procedure and clearances. Please note that these rings are not CARB approved and cannot be shipped to California.
