What material are these JE Pistons made from?

These pistons are forged in the USA using 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 minimizes friction and power loss by using a reduced skirt width. It also saves additional weight with a shorter wrist pin, contributing to overall engine efficiency.

Are these pistons compatible with all 400 SBC engines?

These pistons are designed specifically for 400 SBC engines with a 4.155 inch bore. It's always recommended to verify compatibility with your specific engine build and consult the manufacturer's specifications.

Product Details

Starting with a proprietary Forged Side Relief (FSR) forging design, these JE Pistons for your 400 SBC engine minimize friction and power loss. This design uses a reduced skirt width and a shorter wrist pin, which also helps save weight. They are forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for high-demand performance applications where durability is critical.

Each piston in this set is designed specifically for the 400 SBC engine and its intended use, aiming for optimized performance and longevity. The set includes eight pistons, each with a 4.155-inch bore and a 1.219-inch compression distance. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce pressure from combustion gases, which can prevent ring flutter and improve ring seal for more consistent power delivery. Additionally, a skirt coating might be applied to reduce friction and wear on the piston skirts and cylinder walls, while also helping to lower operating noise.

This piston kit is a solid option for builders looking for proven performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
