Wiseco HD2 Forged Pistons AP Mitsubishi Eclipse 2G DSM 4G63T 100mm stroker 85.5mm -17.7 cc 9.0:1

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.

Wiseco pistons go through more finishing processes than any other piston on the market, without driving the cost up. They come with more features standard than any other piston on the market, at a more affordable price than many of the competitors. All of the Wiseco pistons for this application come standard with anti-friction skirt coating which helps minimize scuffing during break-in and lower friction on the cylinder wall. The top face of the piston is textured to improve the combustion characteristics, and all kits come with rings, pins and locks.

This Piston comes with Wiseco's new Armor Plating Coating. 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.
