Wiseco Chrysler 6.4L Gen III Hemi Apache 4.100in Bore 1.125in CC 0.8661in Pin -9.5 Vol - Set of 8

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for Chrysler's 6.4L Gen III Hemi Apache engine. If you're building a serious race engine or a severe-duty performance street machine, these pistons are designed to handle the extreme demands you'll put on them.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high heat and stress. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal, ensuring efficient combustion and preventing blow-by. The fully machined crown helps with precise volume control, and the forced pin oiling system keeps the wrist pins lubricated under heavy load. Plus, the ArmorGlide skirt coating helps reduce friction and wear, leading to quieter operation and increased seizure resistance.

This set includes eight pistons, each with a 4.100-inch bore and a -9.5cc volume dish, designed to work with a 1.125-inch compression height and a 0.8661-inch pin diameter. They are intended for heavy to severe duty performance builds where durability and consistent performance are critical. Please note that these pistons are not CARB approved and cannot be shipped to California.
