JE Pistons Ring Sets 1.2-1.5-3.0 RINGS

The top ring on this JE Pistons set is made from carbon steel with a plasma moly coating, measuring 0.0472 inches thick. This specific material and thickness are chosen to create a precise seal against the cylinder wall, which is critical for maximizing combustion pressure and, in turn, horsepower. JE Pistons offers these rings in a wide variety of sizes and materials to fit many different engines, and they are known for the same level of sealing that top racing teams rely on.

This set includes a second ring that's 0.0591 inches thick and made from iron phosphate, along with a standard tension oil ring that's 0.1181 inches thick and constructed from carbon steel with a chrome finish. These different materials and thicknesses work together to ensure proper oil control and consistent sealing across the entire piston face. Because these are file-fit rings, they allow for custom sizing to ensure a perfect match for your specific cylinder bore, which is a common practice when rebuilding or modifying engines for optimal performance.
