What material are these JE Pistons made from?

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

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary JE Pistons feature that helps minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, contributing to overall efficiency.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're building a high-performance Mopar 440 Big Block, these JE Pistons are a solid choice. They're designed specifically for this engine, giving you the durability and performance needed for demanding applications. Each piston features a .375 dome to help achieve your desired compression ratio.

JE Pistons has been making forged racing pistons for over 75 years, and these are made 100% in the USA from 2618 aluminum. This material offers the high tensile strength required for serious engine builds. They also incorporate JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to improve ring seal and reduce ring flutter, and a skirt coating to cut down on friction, wear, and noise.

This set includes eight pistons, all forged and machined in the USA. Keep in mind 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.
