JE Pistons 4.6 3V MODULAR 9.5:1 Set of 8 Pistons

If you're rebuilding the engine in your 4.6L 3V Modular Ford, choosing the right pistons is critical for durability and performance. This set of eight pistons from JE Pistons is designed to handle the stresses of high-demand applications, whether you're building a street machine or a dedicated race engine. They are forged in the USA using 2618 aluminum, a material known for its high tensile strength, which is essential for engines that push the limits.

JE Pistons brings over 75 years of experience to their design, and these pistons feature a proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also benefit from a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This set is designed specifically for the 4.6L 3V Modular engine, with a bore of 3.622 inches and a compression ratio of 9.5:1. They are made 100% in the USA, ensuring you're getting a well-built component for your engine build. Please note that these pistons are not CARB approved and cannot be shipped to California.
