JE Pistons Ring Sets - 043-043-3.0-106.426

JE Pistons ring sets are built to maximize horsepower by precisely sealing combustion pressure. This particular set, part number JG7708-4185-5, is designed for 8-cylinder engines and features a file-fit design, allowing for fine-tuning during installation. The top ring is made from 0.043 inch carbon steel with a nitride coating for durability, while the second ring is 0.043 inch ductile iron with a phosphate coating. The oil ring is a low-tension 0.1181 inch carbon steel with a chrome finish, all working together to ensure proper oil control and reduced friction.

JE Pistons is known for using the same advanced ring services that top racing teams rely on, including back cutting and PVD coating, which can lead to significant gains in durability and power. This set is a solid option for engine builds where optimal ring seal and reduced friction are critical for performance. Because these are file-fit rings, they require careful installation to ensure they match the cylinder bore precisely.
