What material are these pistons made from?

These JE Pistons are forged from 2618 aluminum. This material is chosen 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 minimizes friction and power loss. It achieves this by reducing skirt width and using a shorter wrist pin, which also helps save weight.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're building a high-performance 5.4L 3V Modular engine, a set of JE Pistons is a solid choice. These are forged pistons designed specifically for this engine, offering a 9.5:1 compression ratio. JE Pistons has been making performance pistons for over 75 years, and these are built to handle demanding applications.

These pistons are forged in the USA using 2618 aluminum, which gives them the high tensile strength needed for serious performance. They feature JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. Some applications also include an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and more consistent power. If your application includes a skirt coating, it further reduces friction and wear on the piston skirts and cylinder walls, while also quieting down operation.

This set includes eight pistons, each with a 3.572-inch bore and a 0.866-inch wrist pin. They are designed to fit your specific engine and use application for optimized performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California.
