JE Pistons 5.4 4V MODULAR 11:1 Set of 8 Pistons

If you're rebuilding the top end of your 5.4L 4V Modular engine for serious performance, a set of high-quality pistons is crucial. These JE Pistons are built with an 11:1 compression ratio, designed to give your engine a noticeable boost in power and responsiveness when paired with the right setup. They are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when pushing an engine hard.

JE Pistons has been in the game for over 75 years, and they put that experience into these pistons. They feature a proprietary Forged Side Relief (FSR) design that helps minimize friction and power loss by reducing skirt width, and also saves weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure, which improves ring flutter and keeps your rings sealing consistently for reliable power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This set includes eight pistons, all made 100% in the USA. They are designed specifically for the 5.4L 4V Modular engine, ensuring they'll work correctly with your engine's geometry. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a high-performance build, these JE Pistons are a solid choice to form the foundation of your engine's power.
