What material are these JE Pistons made from and why is it important?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is crucial for handling the extreme pressures and temperatures found in high-performance and racing engines.

What is the benefit of the FSR design on these pistons?

The Proprietary Forged Side Relief (FSR) design 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 on the rotating assembly.

Are these pistons compatible with all 400 SBC engines?

These pistons are specifically designed for the 400 small-block Chevy engine with a 4.155-inch bore and a .460-inch dome. It's important to verify that these specifications match your engine's requirements and intended compression ratio.

Product Details

If you're building a high-performance 400 small-block Chevy, JE Pistons offers a well-built set of forged pistons designed to handle the demands of racing and serious street use. This set includes eight pistons, each featuring a .460-inch dome to help achieve your desired compression ratio, and a 4.155-inch bore size. These pistons are crafted from 2618 aluminum, a material chosen for its high tensile strength, making it suitable for engines that push the limits.

JE Pistons brings over 75 years of experience to their forged piston designs, and these are no exception. They are forged and machined entirely in the USA, ensuring a high standard of manufacturing. A notable feature is the Proprietary Forged Side Relief (FSR) design, which uses a reduced skirt width and a shorter wrist pin to minimize friction and save weight, contributing to improved engine efficiency and power output. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, helping to prevent ring flutter and maintain a consistent ring seal for reliable power delivery. Additionally, a skirt coating, if included for your specific application, further reduces friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

This piston set is engineered specifically for the 400 SBC engine and its intended use, aiming for an optimal balance of performance and durability. While these pistons are built for high-demand applications, please note they are not CARB approved and cannot be shipped to California. For installation, refer to the manufacturer's instructions for specific details regarding pin fitment and ring installation.
