ICON premium forged pistons are made from a high-strength, heat treated T6 2618 aluminum alloy. They feature diamond machined skirts and heads for light weight strength in addition to pin bore gas accumulator rings grooves that provide optimal cooling of the piston assembly while it's being compressed during combustion processes within an engine cylinder. With V-rib design features, these lightweight engines get more power out without any maintenance headaches or risk associated with other designs. The best option for you will be ICON. Weigh all your options and choose wisely!
