JE Pistons 4.390 460 FORD FT Set of 8 Pistons

JE Pistons has been a leader in forged racing pistons for over 75 years, and they apply that experience to their domestic engine components. This set of eight pistons is specifically made for 460 Ford FT engines with a 4.390 inch bore. They are engineered and forged in the USA using 2618 aluminum, which offers the high tensile strength needed for demanding performance applications.

These pistons feature JE Pistons' proprietary Forged Side Relief (FSR) design. This helps minimize friction and power loss by reducing skirt width, and the shorter wrist pin also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can improve ring seal and maintain consistent power. Some applications also feature a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, leading to quieter operation and longer life.

This set is designed specifically for the 460 Ford engine and its intended use, aiming for an optimal balance of performance and durability. They are made 100% in the USA. Please note that these pistons are not CARB approved and cannot be shipped to California.
