What material are these JE Pistons made from?

These pistons are forged in the USA from 2618 aluminum. This material is selected for its high tensile strength, which is necessary for high-demand performance applications.

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

The FSR design helps to minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight.

Are these pistons compatible with all 4.6L engines?

This specific set is designed for the 4.6L 3V Modular engine configuration. They are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

JE Pistons is known for its deep experience in forged racing pistons, with over 75 years in the business. They apply this knowledge to their domestic engine components, including this set of 8 pistons for the 4.6L 3V Modular engine. These pistons are built for a 11:1 compression ratio, making them a solid choice for performance builds where increased power is the goal.

Each piston is forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines operating under demanding conditions. JE Pistons uses a proprietary Forged Side Relief (FSR) forging design that helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power delivery. Additionally, a skirt coating can be included to further reduce friction and wear on the piston skirts and cylinder walls, while also contributing to quieter operation.

This set is designed specifically for the 4.6L 3V Modular engine, ensuring optimized performance and durability for its intended use. It's important to note that these pistons are not CARB approved and cannot be shipped to California. They are designed for high-performance applications and are made 100% in the USA.
