What is the advantage of the 2618 aluminum alloy?

The 2618 aluminum alloy is chosen for its high tensile strength. This makes it well-suited for high-demand performance applications where engines experience significant stress and heat, contributing to the pistons' durability.

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 contributes to weight savings by utilizing a shorter wrist pin, which can improve engine responsiveness.

Are these pistons compatible with all 400 SBC engines?

This set is designed for the 400 SBC engine and features a 4.125 inch bore. It's important to verify that these specifications match your engine's requirements and to consult the manufacturer's detailed fitment guide for your specific application.

Product Details

Forged in the USA from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is specifically designed for the 400 SBC engine, featuring an inverted dome design and a 4.125 inch bore. The 2618 aluminum alloy provides the high tensile strength needed to withstand the rigors of performance engines, ensuring durability when you push your vehicle hard.

JE Pistons incorporates their proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, which helps prevent ring flutter and improves ring seal for more consistent power delivery. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes eight pistons, each with a 1.445 inch compression distance and a 0.927 inch pin diameter. The inverted dome has a volume of -36.0 cc. Please note that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, always refer to the manufacturer's installation instructions and recommended assembly procedures.
