JE Pistons Ring Sets 1.2-1.5-3/16

JE Pistons offers this file-fit piston ring set, designed for 8-cylinder engines. These rings are built to create a tight seal in the combustion chamber, which is key to maximizing horsepower. They use a combination of materials for the top, second, and oil rings, aiming for both performance and durability.

The top ring is made from carbon steel with a plasma moly coating, measuring 0.0472 inches thick. The second ring is a 0.0591-inch thick ductile iron phosphate ring. For the oil control, a low-tension 0.188-inch carbon steel chrome ring is used. These are file-fit rings, meaning you'll need to gap them to your specific cylinder bore during installation, a common practice for performance builds to ensure a perfect seal.

JE Pistons is well-known in racing circles, and the same techniques used for top NHRA Pro Stock and NASCAR teams are applied here. This means you're getting a well-built set that can handle demanding use and potentially reduce friction for improved power and longevity. Keep in mind these are not CARB approved and cannot be shipped to California.
