Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% silicon, depending on the application. Pistons are made using gravity cast or hydraulic forging processes, with material structure refined through a hi-tech heat treatment. Machining is done using CNC machines and diamond tools to achieve specific surface finishes. Every Vertex piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with a special Molybdenum Bisulphite black coating for break-in and friction reduction. A new Phosphate Coating offers increased hardness and superior adhesion qualities, extending coating durability. This is a Grade B replica piston with a 53.96mm bore.
