JE Pistons Ring Sets 1.0-1.2-2.8-94.25

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 to help you achieve that seal, maximizing the horsepower your engine can produce. They're built with a combination of materials to handle the demands of the combustion chamber.

This particular set features a 0.0394-inch thick carbon steel nitride top ring and a 0.1102-inch thick carbon steel nitride low-tension oil ring, paired with a 0.0472-inch ductile iron phosphate second ring. These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore size during installation, a common practice for performance builds to ensure a perfect seal. JE Pistons uses the same techniques for these rings as they do for top racing teams, aiming for reduced friction and better durability.

Because these are file-fit rings, they require careful installation to ensure they match your engine's bore. Always refer to the manufacturer's installation instructions for proper gapping and fitting procedures.
