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 Forged Side Relief (FSR) design?

The FSR design is a proprietary feature from JE Pistons that 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.

Are these pistons suitable for street use or only racing?

JE Pistons are known for their performance and durability in racing applications, from dirt tracks to drag strips. While they are built for high-demand scenarios, their design features like skirt coatings (if applicable) can also help reduce noise and wear, potentially making them suitable for certain street performance builds. However, they are not CARB approved and cannot be shipped to California.

Product Details

If you're building a high-performance 400 SBC engine, getting the right pistons is crucial for durability and power. This set of eight dome pistons from JE Pistons is forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for demanding performance applications where reliability is key.

JE Pistons has been a leader in forged racing pistons for over 75 years, and they engineer and machine these pistons 100% in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. Some applications also feature a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also help lower operating noise.

This kit is designed specifically for the 400 SBC engine with a 4.135-inch bore, a 1.000-inch compression distance, and a 0.927-inch pin diameter. These pistons are built for optimal performance and durability in racing environments, from dirt tracks to drag strips. Please note that this part is not CARB approved and cannot be shipped to California.
