JE Pistons Ring Sets 043-043-3.0-117.602

JE Pistons has a long history of building top-tier engine components, especially for racing applications. This piston ring set is a prime example of that expertise, designed to maximize horsepower by ensuring a tight seal for combustion pressure. They come in a wide range of sizes, materials, and thicknesses, so you can find the right fit for many different engines. What's really notable is that JE offers custom services, like back cutting and PVD coating, which are the same techniques used by top NHRA Pro Stock and NASCAR teams. These services can lead to significant improvements in durability, reduced friction for more power, and a better overall ring seal.

This particular set features a 0.043 inch carbon steel nitride top ring, a 0.043 inch ductile iron phosphate second ring, and a 0.1181 inch carbon steel chrome low-tension oil ring. Because these are file-fit rings, they require careful fitting to your specific pistons and cylinder bore, which is a common practice for performance builds where precise sealing is critical. This attention to detail helps ensure optimal performance and longevity for your engine.
