What material are these pistons made from and why is it important?

These pistons are forged from domestic 2618 alloy. This material is chosen for its exceptional strength and ability to perform reliably under the high temperatures and pressures found in performance engines.

What is the purpose of the -23cc dish and the cam/barrel skirt profiles?

The -23cc dish is a specific volume that helps determine your engine's final compression ratio when paired with your cylinder heads and gasket thickness. The cam and barrel skirt profiles are designed to optimize the piston's movement within the cylinder, reducing friction and wear on the cylinder walls while still allowing for efficient power generation.

Are these pistons compatible with all 4.6L/5.4L Ford Modular engines?

These pistons are specifically designed for the 4.6L and 5.4L Ford Modular engines, covering both 2-valve and 4-valve configurations. However, it's always recommended to double-check your specific engine's requirements and consult with your engine builder to ensure perfect compatibility for your build.

About this part

Product Details

Manley Performance is well-known for building robust engine components that stand up to serious use. If you're rebuilding a Ford 4.6L or 5.4L Modular engine, especially the 2-valve or 4-valve versions, these pistons are a solid choice for a high-performance build. They're designed to handle increased power and stress, making them a popular pick for engine builders looking for reliability and improved performance.

These pistons are forged from domestic 2618 alloy, which is a strong material chosen for its ability to withstand high temperatures and pressures without deforming. They feature a -23cc dish, which is important for setting your compression ratio, and a 3.700-inch bore size. Manley also uses proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls, while still allowing the piston to generate power. The ring lands and grooves are machined to strict standards, which helps ensure a good seal for the piston rings, leading to better combustion efficiency and more power.

Included with these pistons are premium chrome moly wrist pins, known for their durability. Manley's manufacturing process is also notable; their unique fixturing allows them to machine the skirt and ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, which is critical for proper ring seal and overall engine health. Keep in mind these are not CARB approved and cannot be shipped to California.
