Wiseco HD2 pistons are specially designed for high-horsepower builds. Wiseco found the parts of pistons that fail when over-powered and beefed them up in those areas like the pin bore, ring lands, crown, etc. They also included a thicker wall pin that will stand up to more abuse than a standard pin. These pistons also come with Asymmetric Skirt AND is Gas Ported! This is definitely the piston to use if you are going to be pushing for big power.
Armor Plated wiseco pistons have almost a bronze colored tint to the top of the piston and the wrist pin bore. Wiseco’s Armor Plating is an abrasion resistant plating that raises the hardness of the aluminum, increases the durability of the ring grooves, prevents micro-welding of the piston rings, reduces carbon buildup and combats corrosion caused by detonation. Wiseco’s most popular pistons now include Armor Plating.
