Wiseco Mitsubishi Evo 4-9 HD2 87.00mm Bore 1.137 in. Compression Height - Single Piston

If you're rebuilding the engine in your Mitsubishi Evo 4-9 for serious performance, you'll want to consider these heavy-duty forged pistons from Wiseco. These pistons are built from 2618 aluminum, a material known for its improved tensile strength, making them a solid choice for demanding builds where reliability is key.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction and resist seizure, contributing to quieter operation and longer life under stress. The fully machined crown and forced pin oiling further show that these are made for heavy to severe duty applications.

Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are sold individually, so be sure to order the correct quantity for your engine.
