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 design helps to 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 Small Block Chevy engines?

This set is specifically designed for the 400 Small Block Chevy engine with a 4.155 inch bore and a .200 inch dome. It's important to confirm these specifications match your engine build before installation.

Product Details

If you're building a high-performance 400 Small Block Chevy engine, JE Pistons offers a well-built set of forged pistons designed to handle the stress. These pistons are crafted from 2618 aluminum, a material known for its high tensile strength, making it ideal for demanding performance applications where durability is key.

JE Pistons applies 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 using a reduced skirt width and a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for more consistent power delivery. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

Every JE Piston is forged and machined 100% in the USA, ensuring a high standard of manufacturing. This specific set is designed for a 4.155 inch bore with a .200 inch dome, and includes a 0.927 inch wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California.
