After nearly 70 years in the business, the name Wiseco has become synonymous with pistons, especially pistons for off-road racing and riding. Wiseco has attained that instant brand recognition by being one of the few manufacturers of forged pistons within the USA.

Details of these specific pistons are as follows:

This Wiseco Piston Kit is designed to fit Mitsubishi 4G63 Engines with a 100mm Stroker Crankshaft and 150mm Long Connecting Rods. These Pistons feature Wiseco's ArmorGlide® Skirt Coating for reduced friction. 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.
