JE Pistons 4.6 4V MOD STRKR 9.5:1 Set of 8 Pistons

If you're building a high-performance 4.6L 4V modular engine, these JE Pistons STRKR series pistons are a solid choice. This set of eight pistons is designed for a 9.5:1 compression ratio, making them suitable for a wide range of performance builds where durability and power are key. JE Pistons has been a leader in forged racing pistons for over 75 years, and this experience is built into every set they produce.

These pistons are forged in the USA using 2618 aluminum, a material known for its high tensile strength, which is essential for handling the demands of performance engines. They feature JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for added weight savings. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, improving ring seal and preventing ring flutter. Some applications also benefit from a skirt coating that further reduces friction and wear, while also quieting down operation.

JE Pistons designs each set specifically for the intended engine and application, ensuring optimized performance and durability. This attention to detail means you're getting a piston that's not just a generic replacement, but a component engineered to work precisely within your 4.6L 4V modular engine. Please note that these pistons are not CARB approved and cannot be shipped to California.
