JE Pistons Ring Sets 1.2-1.2-3mm RING SET

This is a JE Pistons ring set, specifically a 1.2-1.2-3mm set designed for a single cylinder. These rings are file-fit, meaning you'll adjust their end gap to perfectly match your cylinder bore during installation. They are crucial for sealing combustion pressure, which directly impacts your engine's horsepower and overall efficiency.

The top ring is made from carbon steel with a nitride finish, offering good durability and sealing. The second ring is ductile iron with a phosphate coating, further aiding in sealing and heat management. For the oil ring, you get a low-tension carbon steel ring with a chrome face, designed to control oil while minimizing drag. These materials and designs work together to maximize horsepower by ensuring a precise seal.

Because these are file-fit rings, they require careful measurement and adjustment of the end gap to achieve optimal performance and prevent damage to your cylinder walls. This level of customization is often used by professional racing teams for its ability to extract maximum power and durability from an engine.
