Up for sale is a FULL SET of DUCTILE IRON Piston Rings for 8-cylinder engines with pistons that have 3 ring grooves.  These are precision manufactured using the highest quality raw materials and manufacturing techniques. Under a microscope, DUCTILE IRON has round nodular shaped grains that are very strong, unlike the grain structure for plain cast iron rings. Ductile iron is twice as strong as cast iron and is commonly used in high-output, high performance, and high compression situations for this reason. Our rings are easy to install and will provide maximum efficiency over the life of the engine.
