What is the bore size and oversize for these pistons?

These pistons have a bore diameter of 3.937 inches and are .020 inches oversize. This means they are intended for engines that have been bored out to accommodate this larger size.

What material are these pistons made from?

The pistons are forged from a domestic 2618 alloy. This material is chosen for its exceptional strength and performance capabilities, making it suitable for high-stress engine applications.

Are these pistons compatible with all 5.7L Hemi engines?

These pistons are specifically designed for Chrysler 5.7L Hemi engines. However, due to the oversize nature, they are intended for engines that have been machined to accept this size. It is essential to verify compatibility with your specific engine build and consult with your engine builder.

About this part

Product Details

This set includes eight Manley Extreme Duty dome pistons, each measuring 3.937 inches in bore diameter and .020 inches oversize. They feature a 9.3cc dome volume, designed for Chrysler 5.7L Hemi engines. These pistons are crafted from Manley's signature 2618 alloy forgings, a material known for its exceptional strength and ability to handle high performance demands. You'll also find tool steel wrist pins included, which are crucial for connecting the piston to the connecting rod reliably under extreme stress.

Manley's design incorporates proven cam and barrel skirt profiles. This means the piston is shaped to operate smoothly within the cylinder bore, reducing friction and wear while still allowing for substantial power output. The ring lands and grooves are machined to exacting standards, which is vital for achieving a solid seal with your piston rings. This improved seal directly translates to better compression and more power from your engine. The unique fixturing Manley uses allows them to machine the skirt and cut the ring grooves in one operation, ensuring the grooves are perfectly square to the piston skirt for optimal ring function.

These pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance 5.7L Hemi, these Manley pistons are a solid option for durability and power. Remember to consult your engine builder or service manual for specific installation requirements and recommended clearances.
