What material are these JE Pistons made from?

These pistons are forged in the USA from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for high-demand performance applications.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary feature from JE Pistons that helps minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight.

Are these pistons compatible with all 440 engines?

This set is designed for Mopar Big Block 440 engines with a specific 4.350 inch bore. It's important to verify your engine's bore size and application details to ensure proper fitment. Additionally, these pistons are not CARB approved and cannot be shipped to California.

Product Details

If you're building a high-performance Mopar 440 big block, these JE Pistons are a solid choice. This set includes eight pistons specifically designed for your engine, aiming to give you the durability and performance needed for demanding applications. They're forged in the USA using 2618 aluminum, a material known for its high tensile strength, which is crucial when you're pushing an engine hard.

JE Pistons has been making performance pistons for a long time, and they've incorporated some notable features into this set. The proprietary Forged Side Relief (FSR) design helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, you might also find an accumulator groove, which helps reduce combustion gas pressure, leading to better ring seal and more consistent power. Some applications also include a skirt coating that works to reduce friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This kit is designed for a 4.350-inch bore and includes pistons with an inverted dome/dish. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For installation, refer to the manufacturer's instructions for details on proper fitment and assembly.
