JE Pistons 4.6 2V MODULAR 8.5:1 Set of 8 Pistons

If you're building a high-performance 4.6L 2-valve Modular engine, getting the right pistons is crucial for durability and power. This set of eight pistons from JE Pistons is designed specifically for that engine, featuring an 8.5:1 compression ratio that's ideal for forced induction applications or naturally aspirated builds looking for a bit more grunt. JE Pistons has been a leader in forged racing pistons for over 75 years, and they build these right here in the USA.

These pistons are forged from 2618 aluminum, a material known for its high tensile strength, which is exactly what you need when you're pushing an engine hard. They incorporate JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a shorter wrist pin and a narrower skirt. Depending on the specific application, you might also find an accumulator groove to help control 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 cylinder walls, which can also help quiet down engine noise.

This set includes all eight pistons, ready for your build. They are designed for a 3.572-inch bore with a 1.220-inch compression distance and use a 0.866-inch wrist pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For any high-performance engine build, using pistons designed specifically for your engine and intended use, like these from JE Pistons, is a smart move for reliability and performance.
