What material are these JE Pistons made from?

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

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

The FSR design minimizes friction and power loss by reducing skirt width. It also saves weight with a shorter wrist pin, contributing to overall engine efficiency and performance.

Are these pistons compatible with all 5.4L 2V Modular engines?

These pistons are specifically designed for the 5.4L 2V Modular engine family with a 3.562 inch bore and an 8.5:1 compression ratio. Always verify your engine's specifications and consult the manufacturer's fitment guide to ensure compatibility.

Product Details

If you're building a high-performance 5.4L 2-valve Modular engine, this set of eight forged pistons from JE Pistons is a solid foundation. These pistons are designed to handle the stresses of demanding applications, offering a significant upgrade over stock cast pistons. With a compression ratio of 8.5:1, they are well-suited for forced induction setups or high-performance naturally aspirated builds where you need robust components that can take a beating.

JE Pistons has been making performance pistons for over 75 years, and these are forged in the USA from 2618 aluminum. This material choice provides the high tensile strength needed for performance engines. They feature JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear, contributing to both durability and power. Depending on the specific application, these pistons may also include an accumulator groove to improve ring seal and a skirt coating to further reduce friction and noise.

This set includes all eight pistons, ready for installation. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, always refer to the manufacturer's installation instructions and recommended clearances for your specific engine build.
