What makes these pistons suitable for high-performance engines?

These pistons are made from strong 2618 alloy forgings and feature cam and barrel skirt profiles designed for power. They also have precisely machined ring lands for a better seal, contributing to overall engine performance.

What is the benefit of the moly skirt coating?

The moly skirt coating on these pistons helps to reduce friction between the piston skirt and the cylinder wall. This can lead to improved durability and potentially better performance over time.

Are these pistons compatible with all 6.4L Hemi engines?

This specific piston set is designed for 6.4L Hemi engines with a 4.095 inch bore, 6.125 inch rod length, and 4.05 inch stroke. It's important to verify these exact dimensions for your engine build, as variations exist.

About this part

Product Details

If you're building a high-performance Chrysler Hemi 6.4L engine, a solid set of pistons is crucial for handling the demands of serious power. This set of eight forged pistons from Manley Performance is designed for engines with a 4.095 inch bore, a 6.125 inch rod length, and a 4.05 inch stroke, making them a strong choice for engine rebuilds aiming for significant power gains.

Manley uses domestic 2618 alloy forgings, which are known for their strength and ability to perform under high stress, a common requirement for Hemi engines. These pistons feature proven cam and barrel skirt profiles, which help them generate substantial power while also being gentle on your cylinder walls, contributing to a longer engine life. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved combustion efficiency and more power. Select part numbers, like this one, also come with a moly skirt coating, which further reduces friction and enhances durability.

Included with this set are tool steel wrist pins, known for their robustness. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring ultimate squareness between the ring groove and the skirt. This attention to detail is why professional engine builders and tuners often rely on Manley pistons for their builds. Please note that these pistons are not CARB approved and cannot be shipped to California.
