What material are these Manley pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it well-suited for demanding engine applications.

What is the significance of the -12cc dish and 4.0200-inch bore?

The -12cc dish is a specific volume designed into the piston crown, which affects the compression ratio when paired with your cylinder heads. The 4.0200-inch bore is the exact diameter of the piston, matching the cylinder bore size it will operate within.

Are these pistons compatible with all Ford Raptor 6.2L engines?

These pistons are specifically designed for the Ford Raptor 6.2L SOHC 2 Valve engine. They are not CARB approved and cannot be shipped to California. Always confirm fitment with your specific engine build and local regulations.

About this part

Product Details

Forged from domestic 2618 alloy, these Manley pistons are built for serious performance in your Ford Raptor's 6.2L engine. They feature a -12cc dish and a 4.0200-inch bore, designed to work with the SOHC 2-valve configuration. If you're rebuilding the top end of your Raptor's engine, especially if you're aiming for more power or need to replace worn-out components, these pistons offer a solid foundation.

Manley uses proven cam and barrel skirt profiles that help generate power while also being considerate of your cylinder walls, which can make for a smoother break-in and longer engine life. The ring lands and grooves are machined to strict standards, which is crucial for getting a good seal from your piston rings. A good ring seal means better compression and more efficient combustion. For added durability, these pistons come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for consistent performance.

This set is intended for performance builds and is not CARB approved, meaning it cannot be shipped to California. If you're looking to get the most out of your 6.2L Raptor engine, these well-built pistons are a popular choice among professional engine builders for their strength and reliability.
