What material are these pistons made from?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary to withstand the demands of high-performance engine applications.

Are these pistons compatible with all 4.6L 3V engines?

These pistons are specifically designed for the 4.6L 3V modular engine. While they are a direct fit for the bore size and pin diameter, it's always recommended to confirm compatibility with your specific engine build and any modifications you may have.

What is the purpose of the Forged Side Relief (FSR) design?

The FSR design helps to minimize friction and power loss by reducing skirt width. It also contributes to weight savings by utilizing a shorter wrist pin, making the piston assembly more efficient.

Product Details

If you're building a high-performance 4.6L 3V modular engine, you need pistons that can handle the stress. This set of eight forged pistons from JE Pistons is designed to give you the durability and performance needed for demanding applications. They are forged and machined right here in the USA, using 2618 aluminum, which offers the high tensile strength required for serious engine builds.

JE Pistons has been making performance pistons for over 75 years, and they've put that experience into this set. They feature a proprietary Forged Side Relief (FSR) design that helps reduce friction and skirt wear, saving weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure for better ring seal, and a skirt coating to further reduce friction and noise. These pistons are made specifically for the 4.6L 3V engine, ensuring optimized performance and durability.

This set includes eight pistons with a 9.5:1 compression ratio, a 3.562-inch bore, and a 0.866-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds and are a solid choice when you need reliable components for your engine.
