JE Pistons Ring Sets 1.2-1.5-3.0 RINGS

Starting with a 0.0472 inch thick carbon steel plasma moly top ring, this JE Pistons ring set is built for serious sealing. This set is designed for 8-cylinder engines and uses a file-fit approach, meaning you can precisely tailor the ring gap to your specific engine build. The second ring is 0.0591 inches thick and made of iron phosphate, while the oil ring is a low-tension carbon steel chrome design at 0.1181 inches. This combination is aimed at maximizing horsepower by ensuring a tight seal against combustion pressure.

JE Pistons is known for working with top racing teams, and the technology in these rings reflects that. The plasma moly top ring offers improved durability and reduced friction, which translates to more power and a better seal over time. Because these are file-fit rings, they offer a unique advantage for builders who need to achieve a perfect fit for their specific bore size and application, especially in high-performance or custom engine builds. This level of precision is what helps prevent blow-by and keeps your engine running efficiently.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your engine and need a reliable, high-performance ring set, this JE Pistons offering is a solid option.
