Mahle MS Custom Piston Set Ford 6.4L 3.866in Bore (Must Provide Custom Specs for Pistons)

These Mahle MS Custom Piston sets start with a forged aluminum construction, a strong foundation for high-performance diesel engines. Because they are made to order, you can specify the exact dimensions and features needed for your particular Ford 6.4L Powerstroke build. This means you get pistons tailored precisely to your engine's requirements, whether you're aiming for maximum power, improved durability, or a specific compression ratio. The 3.866-inch bore size is a key measurement that ensures a proper fit within the cylinder block, and the 388 cubic inch displacement indicates the engine size these pistons are designed for.

The 'MS Custom' designation means these aren't off-the-shelf parts. Mahle works with you to define the exact specifications, ensuring these pistons integrate seamlessly into your engine's overall design. This level of customization is crucial for builders who need precise control over their engine's performance characteristics. Forged aluminum offers a significant advantage over cast pistons, providing superior strength and resistance to deformation under extreme cylinder pressures commonly found in modified diesel applications.

Because these pistons are custom-made, it's essential to contact us to discuss your specific needs and provide the necessary custom specifications before ordering. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Proposition 65 warning.
