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 engine 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, which also contributes to saving weight.

Are these pistons compatible with all 400 SBC engines?

This set is designed specifically for 400 SBC engines. However, they are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

When you're rebuilding a high-performance 400 SBC engine, the pistons are critical for handling the stress and delivering power. This set of eight forged pistons from JE Pistons is built to meet the demands of serious performance applications, whether you're on the track or the street.

Crafted from 2618 aluminum right here in the USA, these pistons offer the high tensile strength needed for engines pushed to their limits. JE Pistons incorporates their proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to manage combustion gas pressure, leading to better ring seal and consistent power, and a skirt coating to further reduce friction and wear while quieting operation.

This set is designed specifically for the 400 SBC engine, ensuring optimized performance and durability. Remember that these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have all necessary supporting components and refer to manufacturer instructions for proper installation.
