JE Pistons Ring Sets 1.0-1.2-2.8-3.228

With this set, you get a complete piston ring kit designed for 4-cylinder engines. It includes a 0.0394-inch carbon steel nitride top ring, a 0.0472-inch ductile iron phosphate second ring, and a 0.1102-inch low-tension carbon steel nitride oil ring. These rings are file-fit, meaning you'll need to gap them to your specific pistons and cylinder bore during installation, which is a common practice for performance builds to ensure a perfect seal.

JE Pistons designed these rings to maximize horsepower by precisely sealing combustion pressure. The materials used, like the carbon steel nitride for the top and oil rings and ductile iron phosphate for the second ring, are chosen for their durability and ability to maintain a tight seal under high temperatures and pressures. This attention to sealing helps prevent blow-by, ensuring that more of your engine's power makes it to the crankshaft. The low-tension oil ring is also a notable feature, designed to reduce drag and further improve efficiency.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. If you're rebuilding a performance 4-cylinder engine and want to ensure optimal combustion sealing, this set from JE Pistons is a solid option.
