These OE-quality Sealed Power cast piston rings are made from ductile iron and are specifically designed for stock rebuilds. The top rings are barrel-shaped to help seal against blowby. The second rings have a taper that faces the bottom of the cylinder bore and seals against the oil control rings' upper surface, providing excellent oil control.
