What is included in this piston set?

This set includes eight JE Pistons, each with a 3.622-inch bore, 1.320-inch compression distance, and a 0.866-inch wrist pin. The pistons have an inverted dome/dish design contributing to the 8.5:1 compression ratio.

What material are these pistons made from and why is it important?

These pistons are forged in the USA from 2618 aluminum. This material is selected for its high tensile strength, which is necessary to withstand the demands of high-performance engine applications.

Are there any special features on these pistons?

Yes, they feature JE's proprietary Forged Side Relief (FSR) design to reduce friction and weight. Depending on the specific application, they may also include an accumulator groove for improved ring seal and a skirt coating to reduce friction and noise.

Product Details

This is a set of eight JE Pistons, specifically designed for the 5.4L 3-valve Modular engine with a compression ratio of 8.5:1. You'll receive eight pistons, each measuring 3.622 inches in bore diameter, with a 1.320-inch compression distance and a 0.866-inch wrist pin. These pistons feature an inverted dome/dish design with a volume of -33.5cc, contributing to the overall 8.5:1 compression ratio.

JE Pistons are forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, making these pistons well-suited for high-demand performance applications. They incorporate JE's proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, improve ring flutter, and enhance ring seal for consistent power. Some applications also feature a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, which can also help lower operating noise.

These pistons are made 100% in the USA and are engineered specifically for the 5.4L 3-valve Modular engine to provide an optimized combination of performance and durability. Please note that this part is not CARB approved and cannot be shipped to California.
