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 crucial for high-demand performance applications.

What is the purpose of the Forged Side Relief (FSR) design?

The FSR design minimizes friction and power loss by reducing the piston skirt width. It also utilizes a shorter wrist pin, which helps save additional weight on the piston assembly.

Are these pistons legal for use in California?

No, this product is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

JE Pistons is known for its forged racing pistons, bringing over 75 years of experience to domestic engine builds. This set of eight pistons is specifically crafted for the 400 SBC engine, featuring a .200-inch dome to optimize compression for performance applications. Engineered, forged, and machined entirely in the USA, these pistons are built to handle the rigors of high-demand use.

Constructed from 2618 aluminum, these pistons offer the high tensile strength necessary for demanding performance builds. They incorporate JE Pistons' proprietary Forged Side Relief (FSR) design, which minimizes friction and power loss through a reduced skirt width and a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to reduce combustion gas pressure, improving ring seal and preventing flutter, and a skirt coating to further reduce friction and wear while quieting operation.

This piston set is designed for a 4.165-inch bore with a 1.425-inch compression distance and a 0.927-inch pin. Please note that this product is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
