What is the compression height for these pistons?

These Wiseco pistons have a compression height of 1.110 inches. This measurement is critical for achieving the correct piston-to-head clearance and desired compression ratio in your engine build.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these pistons helps to reduce friction between the piston skirt and cylinder wall. This can lead to improved performance, quieter operation, and increased resistance to seizure under high loads.

Are these pistons compatible with all 6.4L Hemi engines?

These pistons are specifically designed for the Gen3 Hemi version of the 6.4L engine. It is essential to verify compatibility with your specific engine model and year, as variations can exist.

Product Details

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty engine builds. The 4.090-inch bore size is specific for Chrysler 6.4L Gen3 Hemi engines, and the 0.927-inch pin diameter is a common size for high-performance applications. Wiseco machines these pistons in the USA, ensuring precise manufacturing for critical engine components.

Wiseco's Professional Series pistons are packed with features aimed at durability and performance under severe conditions. They include precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The piston crown is fully machined for a clean combustion chamber surface, and forced pin oiling helps keep the wrist pin lubricated. Additionally, these pistons come with an ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation.

This set includes eight pistons, enough for a complete V8 engine. While designed for heavy to severe duty race applications, it's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper fitment and assembly procedures.
