JE Pistons Ring Sets .043-.043-3.0-117.221

This piston ring set includes the components you need for an 8-cylinder engine rebuild. You get a .043 inch carbon steel nitride top ring, a .043 inch ductile iron phosphate second ring, and a .1181 inch carbon steel chrome low tension oil ring. These rings are file-fit, meaning you'll adjust them to your specific cylinder bore during installation for a precise seal.

JE Pistons designs these rings to maximize horsepower by ensuring a tight seal for combustion pressure. The carbon steel nitride top ring offers good durability and heat resistance, while the ductile iron phosphate second ring helps with oil control and combustion sealing. The low tension chrome oil ring is designed to reduce drag, which can contribute to improved power and better oil management. These are the same types of rings used by professional racing teams, indicating a focus on performance and durability.

Because these are file-fit rings, they require careful measurement and adjustment to match your engine's cylinders. This ensures optimal performance and longevity. Please note that these rings are not CARB approved and cannot be shipped to California.
