JE Pistons 440 MOPAR FT Set of 8 Pistons

If you're building a high-performance Mopar 440 Big Block engine, you need pistons that can handle the stress. This set of eight forged pistons from JE Pistons is designed specifically for that kind of demanding application. They're made from 2618 aluminum, a material known for its high tensile strength, which is crucial when you're pushing an engine hard, whether that's on the drag strip or in a street-performance build.

JE Pistons brings over 75 years of experience to the table with these components, and they're forged and machined entirely in the USA. You'll find features like their proprietary Forged Side Relief (FSR) design, which helps reduce friction and save weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving the seal for consistent power. Some applications also benefit from a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

This set includes pistons with a flat top design, a 4.375-inch bore, and a 0.990-inch wrist pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For serious Mopar engine builds, these JE Pistons offer a well-built foundation for durability and performance.
