JE Pistons 5.4 3V MODULAR 9.5:1 Set of 8 Pistons

If you're building a high-performance 5.4L 3V Modular engine, a solid set of pistons is crucial. This set from JE Pistons is designed for a 9.5:1 compression ratio, making it a great choice for boosted applications or naturally aspirated builds looking for a balance of power and reliability. JE Pistons has been a leader in forged racing pistons for over 75 years, and this set reflects that experience, offering a well-built component for demanding engine builds.

These pistons are forged in the USA using 2618 aluminum, a material known for its high tensile strength, which is essential for handling the stresses of performance engines. They feature JE Pistons' proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, which helps prevent ring flutter and improves ring seal for consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes eight pistons, each with a 3.552-inch bore and a -19.7cc dish volume, contributing to the 9.5:1 compression ratio. The included wrist pins are 0.866 inches in diameter. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For any performance engine build, using pistons specifically designed for your engine and intended use, like these from JE Pistons, is key to achieving optimal performance and durability.
