JE Pistons Ring Sets 1.0-1.2-2.8-3.701

Starting with a 0.0394-inch thick carbon steel nitride top ring, this JE Pistons ring set is built for serious engine work. These rings are designed to create a tight seal in the cylinder bore, which is crucial for maximizing horsepower by keeping combustion pressure where it belongs. The set also includes a 0.0472-inch ductile iron phosphate second ring and a low-tension 0.1102-inch carbon steel nitride oil ring, all engineered to work together for optimal engine performance.

This is a file-fit set, meaning you'll need to gap the rings yourself to precisely match your cylinder bore dimensions. This level of customization is common in performance builds and allows for a more accurate seal than pre-gapped rings. JE Pistons uses the same ring services, like PVD coating and back cutting, that are trusted by top NHRA Pro Stock and NASCAR teams, aiming for improved durability and reduced friction for more power.

Because these rings are not CARB approved, they cannot be shipped to California. If you're rebuilding an 8-cylinder engine and need a precise, high-performance ring setup, this JE Pistons set offers a well-built option with advanced materials.
