What is the compression ratio achieved with these pistons?

This set of pistons is designed to achieve an 8.5:1 compression ratio. This is a common ratio for performance builds that require a balance between power and pump gas compatibility.

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

These pistons are specifically designed for the 5.4 2V Modular engine platform. While they are a direct fit for the bore size and intended application, it's always recommended to verify compatibility with your specific engine code or build requirements.

What materials are used in the construction of these pistons?

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.

Product Details

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications like your 5.4 2V Modular engine. This set includes eight pistons designed to achieve an 8.5:1 compression ratio, making them a solid choice for builds where you're looking for robust power and durability under stress.

JE Pistons brings over 75 years of experience to the table, and these pistons are forged and machined entirely in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for added weight savings. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power delivery. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down operating noise.

This set is engineered specifically for the 5.4 2V Modular engine, with a 3.622-inch bore and a -41.5cc inverted dome. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, JE Pistons are a well-known name, and this set offers a strong foundation for your project.
