What material are these pistons made from?

These pistons are forged from 2618 aluminum. This material is chosen for its improved tensile strength, making it well-suited for high-performance and heavy-duty applications.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide coating on the piston skirts serves multiple purposes. It helps reduce friction between the piston and cylinder wall, contributes to quieter operation, and offers resistance to seizure.

Are these pistons compatible with all 6.4L HEMI engines?

This set is specifically designed for the Chrysler 6.4L Gen3 HEMI engine with a 4.090 inch bore. It is important to confirm that these specifications match your engine's requirements, as it is not CARB approved and cannot ship to California.

Product Details

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who need top-tier durability and performance for their Chrysler 6.4L Gen3 HEMI engine.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding conditions. They come packed with features like precision ring grooves, an anti-detonation groove, and extra ring seal improvements to ensure a solid seal under pressure. The fully machined crown and forced pin oiling are also key details that contribute to their robust design for heavy to severe duty race builds. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure.

This set includes eight pistons, all machined to a 4.090-inch bore size. Keep in mind these are not CARB approved and cannot be shipped to California. For builders pushing the limits of their HEMI, these pistons are designed to help you remove your limits.
