What does 'file-fit' mean for these piston rings?

File-fit rings need to be gapped by the installer to match the specific cylinder bore size of your engine. This ensures a proper seal and is a common practice for performance engine builds.

What are the benefits of the carbon steel nitride and ductile iron phosphate materials?

Carbon steel nitride is chosen for its durability and sealing capabilities, especially for the top and oil rings. Ductile iron phosphate in the second ring helps with oil control and preventing blow-by, contributing to overall engine health and performance.

Are these rings compatible with all 4-cylinder engines?

These rings are designed for 4-cylinder engines and come in specific sizes. It's important to verify the exact dimensions and application against your engine's specifications to ensure a correct fit.

Product Details

JE Pistons Ring Sets JG1004-2953 are a solid option for your 4-cylinder engine build. These rings are built to seal combustion pressure effectively, which is key to making the most horsepower. They come in a specific set of sizes, with a 0.0394-inch carbon steel nitride top ring, a 0.0472-inch ductile iron phosphate second ring, and a 0.1102-inch carbon steel nitride low-tension oil ring.

The materials chosen here are meant to balance sealing and friction. The carbon steel nitride top and oil rings offer good durability and sealing performance, while the ductile iron phosphate second ring helps with oil control and blow-by. JE Pistons is known for working with top racing teams, and the technology they use in those applications often trickles down to their street-level products, offering improved durability and reduced friction for better power output.

Remember that these rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation. This is a standard practice for performance builds to ensure optimal sealing. Also, note that these are not CARB approved and cannot be shipped to California.
