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 necessary for high-demand performance applications.

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

The FSR forging design helps to minimize friction and power loss. It achieves this by reducing the piston skirt width and utilizing a shorter wrist pin, which also saves weight.

Are these pistons compatible with all 400 SBC engines?

This set is designed for 400 Small Block Chevy engines with a 4.040-inch bore. It's always recommended to verify specific engine build requirements and clearances before installation.

Product Details

If you're building a high-performance 400 Small Block Chevy, JE Pistons offers a set of flat-top pistons designed to handle the demands of serious engine work. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for engines that push the limits.

JE Pistons brings over 75 years of experience to their forged piston designs. This set features a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. They also use a shorter wrist pin to save additional weight. Depending on the specific application, these pistons may include an accumulator groove to help reduce combustion gas pressure, which can improve ring seal and prevent fluttering. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life.

This set is specifically designed for the 400 SBC engine, with a 4.040-inch bore and flat-top design. They are made 100% in the USA, ensuring a high standard of manufacturing. Please note that these pistons are not CARB approved and cannot be shipped to California.
