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

If you're building or rebuilding a 4.6L 3V Modular engine and need a solid set of pistons for a high-performance application, JE Pistons has you covered. This set of eight pistons is designed with an 8.5:1 compression ratio, making them a great choice for forced induction builds or naturally aspirated engines where you want a bit more control over detonation. JE Pistons brings over 75 years of experience to the table, and these pistons are forged, engineered, and machined right here in the USA.

What sets these pistons apart is their construction and design features. They're made from 2618 aluminum, a material known for its high tensile strength, which is exactly what you need when you're pushing an engine hard. JE Pistons also incorporates their proprietary Forged Side Relief (FSR) forging design. This 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, you might also find an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also quiet down the engine's operation.

These pistons are designed specifically for the 4.6L 3V Modular engine, ensuring they'll work correctly with your existing components. They feature an inverted dome/dish design and have a bore size of 3.572 inches, a compression distance of 1.220 inches, and a wrist pin size of 0.866 inches. Keep in mind that this set is not CARB approved and cannot be shipped to California. If you're looking for durable, high-performance pistons that are built to last in demanding conditions, this set from JE Pistons is a well-built option.
