What material are these pistons made from and why is it important?

These pistons are forged from 2618 aluminum. This material offers improved tensile strength compared to cast aluminum, making it better suited for the high pressures and temperatures found in severe duty race applications.

What is the ArmorGlide skirt coating for?

The ArmorGlide coating on the piston skirts helps to reduce friction between the piston and cylinder wall. This leads to quieter operation, less wear, and improved resistance to seizure, which is critical for engine longevity under heavy load.

Are these pistons compatible with all 6.4L Hemi engines?

These pistons are specifically designed for the Chrysler 6.4L Gen3 Hemi engine with a 4.100 inch bore. It's always recommended to confirm the specific dimensions and requirements for your engine build to ensure proper fitment.

Product Details

If you're rebuilding the heart of your Chrysler 6.4L Gen3 Hemi for serious racing or heavy-duty performance, a strong set of pistons is where you start. These Professional Series pistons from Wiseco are built with the kind of attention to detail that serious engine builders demand. They're forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to handle the intense pressures of high-performance applications.

Wiseco didn't stop there. You'll find precision ring grooves designed for better sealing, an anti-detonation groove to help prevent damage, and features that further improve ring seal. Plus, they come with an ArmorGlide skirt coating. This coating helps reduce friction, makes operation quieter, and resists seizure, all crucial for longevity in demanding builds. The fully machined crown is ready for whatever you throw at it, and forced pin oiling ensures the wrist pins stay well-lubricated under extreme conditions.

This set includes eight pistons, each with a 4.100-inch bore and a 1.110-inch compression height, using a 0.8661-inch pin diameter. Keep in mind these are intended for heavy to severe duty race builds and are not CARB approved, so they cannot be shipped to California. If you're aiming to push the limits of your Hemi, these pistons are a solid foundation.
