Wiseco Chrysler 6.4L Gen III Hemi Apache 4.090in Bore 6.200in Rod 0.945in Pin -11.5 Vol - Set of 8

If you're building a serious performance engine for your Chrysler 6.4L Gen III Hemi, these Wiseco Professional Series forged pistons are a solid choice. Designed for heavy to severe duty race applications, these pistons are built to handle significant power and stress. They feature a 4.090 inch bore and are sold as a set of eight, ready to be installed in your Apache engine.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for high-performance builds. The machining process includes precision ring grooves, an anti-detonation groove, and features designed to enhance ring seal for better combustion efficiency. They also come with forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions. For added durability and reduced friction, these pistons include an ArmorGlide skirt coating, which helps resist seizure and operate more quietly.

These pistons are designed with a -11.5cc volume, which is important for achieving your desired compression ratio when paired with the right cylinder heads and gasket. The fully machined crown ensures a clean and precise combustion chamber surface. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct connecting rods and other supporting components to match these high-performance pistons.
