What material are these pistons made from?

These Manley Platinum Series pistons are forged from a domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it well-suited for high-output engine builds.

What is the purpose of the cam and barrel skirt profiles?

The cam and barrel profiles on the piston skirts are designed to optimize the piston's movement within the cylinder. This design helps to generate substantial power while also minimizing friction and wear on the cylinder walls, contributing to engine longevity.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California. They are intended for use in vehicles where emissions compliance is not a requirement, such as racing or off-road applications.

About this part

Product Details

If you're building a high-performance Chrysler Hemi 5.7L engine, these Manley Platinum Series pistons are a solid choice for your stroker build. They're designed with a 3.922-inch bore and a 4.050-inch stroke, specifically intended to increase displacement and power output for your Hemi.

Manley uses domestic 2618 alloy forgings for these pistons, which means they're built for serious strength and durability under demanding conditions. The pistons feature proven cam and barrel skirt profiles that help generate more power while also being gentler on your cylinder walls, reducing wear over time. You'll also find exacting standards applied to the ring lands and grooves, which is crucial for getting a good seal with your piston rings, leading to better compression and more power. They come standard with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, a detail that matters for consistent performance.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are intended for off-road or racing applications where emissions compliance is not a factor. For a build that demands reliable power and longevity, these Manley pistons are a well-built option.
