What material are these pistons made from?

These pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and ability to perform under high pressure and temperature conditions common in performance engines.

What is the purpose of the -24cc dish and what compression ratio does it create?

The -24cc dish is a feature of the piston crown that helps to lower the overall compression ratio. In a 4.080-inch bore, this dish helps achieve a 9.09:1 compression ratio, which is suitable for many modified Hemi applications.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California. It is important to check local emissions regulations before purchasing and installing engine components.

About this part

Product Details

Manley Performance is well-known for building strong engine components that professional builders trust. If you're working on a Chrysler 6.1L Hemi and need a reliable set of pistons, these are a solid option. They're designed to handle the demands of a performance build, offering improved strength and durability over stock components.

These pistons are forged from domestic 2618 alloy, which is a strong material chosen for its ability to withstand high pressures and temperatures. They feature a -24cc dish, which helps achieve a 9.09:1 compression ratio when installed in a 4.080-inch bore, a common setup for modified Hemis. The skirt profiles are carefully shaped to reduce friction and wear on your cylinder walls while still making good power. Manley also pays close attention to the ring lands and grooves, ensuring a tight seal for better combustion efficiency and more power. The included wrist pins are made from Chrome Moly for added durability.

This set includes eight pistons, enough for a complete V8 engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For installation, you'll want to refer to the manufacturer's instructions for precise details on ring gap, piston-to-wall clearance, and assembly.
