JE Pistons Ring Sets 1.2-1.5-3.0-103.632

JE Pistons Ring Sets JG3108-4075-5 are built for 8-cylinder engines, designed to seal combustion pressure effectively and help you get the most horsepower out of your build. These rings are file-fit, meaning they require a bit of adjustment during installation to achieve a perfect gap for your specific cylinder bore. This attention to detail is what top racing teams rely on for maximum performance and durability.

The top ring is made from carbon steel with a nitride treatment, chosen for its strength and ability to handle high combustion temperatures. Beneath that, the second ring is constructed from iron phosphate, which works with the top ring to ensure a solid seal. For the oil control, a low-tension carbon steel chrome ring is used, designed to manage oil efficiently while minimizing drag for improved power. These materials and designs are the same kind used by professional racing teams, offering a significant boost in durability and reduced friction.

Because these rings are file-fit, it's important to have the right tools and knowledge for installation, or to have a trusted mechanic handle the job. This set is not CARB approved and cannot be shipped to California.
