The front shape of the white piston head has been designed to generate a light air cone that ensures better and greater compression of the air volume inside the cylinder. The stroke on the cylinder head PAD is reduced compared to other piston heads on the market of other manufacturers, to better and more gradually distribute the impact given by the stroke of the piston. The total height of the TopMax piston head is standardized to the size of the other piston heads on the market. The ERGAL and DELRIN insert for fixing the piston head on the piston, specific for Marui SRE platform, is CNC made and it has a new design that reduce the overhall weight of the piston head, reducing the striking mass too. For maximum performance, we recommend pairing the piston head with the TopMax cylinder head.
