JE Pistons Ring Sets 91.50mm Bore 1.0mm Top Ring 1.2mm Second Ring 2.8mm Oil Ring

JE Pistons offers this piston ring set, designed for a 91.50mm bore, to help you get the most out of your engine. These rings are built to seal combustion pressure effectively, which is key to maximizing horsepower. They come in a 1.0mm top ring, 1.2mm second ring, and a 2.8mm oil ring configuration, suitable for a variety of engine builds.

The top and oil rings are made from carbon steel with a nitride finish for durability, while the second ring is ductile iron with a phosphate finish. This combination is chosen to balance sealing performance with reduced friction. JE Pistons uses the same types of ring services, like back cutting and PVD coating, that are utilized by professional racing teams to improve durability and power.

This set is a file-fit type, meaning you'll need to gap the rings to your specific application during installation. This allows for a precise fit in your cylinder bores, ensuring optimal performance. Please note that these rings are not CARB approved and cannot be shipped to California.
