JE Pistons Ring Sets 1.0-1.2-2.8-3.189

When you're rebuilding the top end of your engine, getting the piston rings seated correctly is crucial for sealing combustion pressure. This set from JE Pistons is designed for that job, offering a file-fit design so you can achieve a precise gap for your specific cylinder bore. They're built with a 0.0394-inch carbon steel nitride top ring and a 0.0472-inch ductile iron phosphate second ring, which work together to manage blow-by and maintain compression.

The oil control ring is a low-tension, 0.1102-inch carbon steel nitride design, helping to keep oil consumption in check. JE Pistons uses the same materials and processes for these rings as they do for top racing teams, aiming for improved durability and reduced friction. The file-fit nature means you'll need to carefully measure and file the end gap to match your engine's bore size, ensuring a perfect seal.

Because these are file-fit rings, they offer a lot of flexibility for various engine builds. Just remember that they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper gapping and fitting procedures.
