JE Pistons 4.6 3V MODULAR 8.5:1 Set of 8 Pistons

If you're rebuilding the engine in your 4.6L 3V Modular Ford, especially for a high-performance application, a solid set of pistons is crucial. These JE Pistons are built for demanding use, offering a robust 8.5:1 compression ratio that's ideal for forced induction setups or high-performance naturally aspirated builds. They are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making these pistons well-suited for the stresses of performance engines.

JE Pistons brings over 75 years of experience to the table with these components. 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 weight savings. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure, improving ring seal and maintaining consistent power. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

This set includes eight pistons, designed specifically for the 4.6L 3V Modular engine. They feature an inverted dome/dish design with a 3.622-inch bore, a 1.220-inch compression distance, and an 0.866-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
