JE Pistons 440 MOPAR FT -3CC Set of 8 Pistons

This is a set of eight JE Pistons, specifically designed for Mopar Big Block engines with a 4.350-inch bore. You get flat-top pistons with a -3cc dish volume, ready to be installed in your performance build. These pistons are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making it well-suited for the demands of high-performance racing applications.

JE Pistons has incorporated their proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for more consistent power delivery. Some applications also benefit from a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

Because these pistons are engineered specifically for each engine and use application, they are optimized for performance and durability. This set is not CARB approved and cannot be shipped to California.
