What material are these pistons made from?

These Manley Street Master 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 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 reduce friction and wear on the cylinder walls, contributing to both improved performance and longer engine life.

Are these pistons suitable for all engine builds?

These pistons are designed for performance applications and are not CARB approved, meaning they cannot be shipped to California. They are a solid option for engine builders looking for strength and durability in their 4.6L or 5.4L Ford modular engines.

About this part

Product Details

If you're rebuilding the engine in your 1996-2004 Ford Mustang, especially for a performance application, a solid set of forged pistons is crucial. These Manley Street Master dish pistons are built to handle the demands of modified 4.6L and 5.4L 2-valve and 4-valve engines. They feature a 3.582-inch bore size, which is a common starting point for many performance builds.

Manley uses domestic 2618 alloy forgings for these pistons, which offers a strong foundation for increased horsepower and torque. The pistons are designed with proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls, even under stress. You'll also find exacting standards for the ring lands and grooves, which is key for achieving a good seal and maximizing power output. Each set includes premium chrome moly wrist pins for added durability.

These pistons are a popular choice among professional engine builders because of their well-built construction and the attention to detail in their design. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other. This level of precision contributes to better engine performance and longevity. Please note that these pistons are not CARB approved and cannot be shipped to California.
