What is the compression ratio of these pistons?

These JE Pistons feature a 9.5:1 compression ratio. This is a common ratio for performance builds, offering a good balance for naturally aspirated or forced induction setups.

What material are these pistons made from?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for the demanding conditions found in high-performance engines.

Are these pistons compatible with all 4.6 2V Modular engines?

While designed for the 4.6 2V Modular platform, specific applications may vary. It's always best to verify fitment details with the manufacturer's data to ensure compatibility with your exact engine build and intended use.

Product Details

If you're rebuilding the top end of your 4.6 2V Modular engine for serious performance, a strong set of pistons is where you start. These JE Pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for high-demand applications where durability and consistent power are critical. They're made 100% in the USA, carrying on JE Pistons' long history of providing proven performance for racing and high-output engines.

JE Pistons uses a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width. This design also saves weight, especially when paired with a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This set includes eight pistons, each designed specifically for the 4.6 2V Modular engine to optimize performance and durability. The 9.5:1 compression ratio is a popular choice for naturally aspirated or forced induction builds where a balance between power and pump gas compatibility is desired. Please note that these pistons are not CARB approved and cannot be shipped to California.
