This Wiseco Piston Kit features the all new HD2 / Asymmetric Skirt Forging. This is the strongest forging available for the 4G63 Engines. The Asymmetric Skirt has a standard skirt width on the thrust side, but a much smaller skirt width on the non-thrust side. This allows extra material to be added where it is needed, without adding weight. These Pistons will fit both EVO and DSM 2G 7 Bolt Engines. They will also fit a 4G64 Block w/ a 4G63 / EVO Head.  Included in this kit are .200" Wall Wrist Pins and a Matching Piston Ring Set. The Piston Rings feature a Gas Nitrided Top Ring that works very well with Turbocharged Engines and a Napier 2nd Ring for Excellent Oil Control. These Pistons feature Wiseco's ArmorGlide® Skirt Coating for reduced friction and Wiseco's Armour Plating Finishing Process. The Armour Plating drastically strengthens the Piston Material, making it harder the hotter it gets. This helps resist any possible detonation and also helps the Piston Rings from Micro Welding under extreme temperatures.
