JE Pistons Ring Sets 1.2-1.2-3mm MOLY

When you're rebuilding an engine, getting the piston rings right is crucial for sealing combustion pressure and maximizing horsepower. This JE Pistons Moly Piston Ring Set, part number J92608-4030-5, is designed for 8-cylinder applications and features a file-fit design, meaning you can precisely tailor the end gap to your specific cylinder bore for optimal sealing.

This set includes a 0.0472-inch (1.2mm) carbon steel plasma moly top ring, known for its durability and ability to handle high combustion temperatures. The second ring is a 0.0472-inch (1.2mm) ductile iron phosphate ring, which helps control oil consumption and further aids in sealing. For the oil ring, you get a 0.1181-inch (3mm) carbon steel chrome low-tension design, engineered to effectively scrape oil from the cylinder walls without creating excessive drag, contributing to reduced friction and improved power.

JE Pistons is well-known for the same high-performance ring services used by top racing teams, and this set benefits from that expertise. While these rings are not CARB approved and cannot be shipped to California, they represent a solid option for engine builds where precise sealing and durability are key.
