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 essential for high-performance engine applications that experience significant stress and heat.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary forging technique used by JE Pistons. It helps to minimize friction and power loss by reducing the piston skirt width and using a shorter wrist pin, which also saves weight.

Are these pistons suitable for a street-driven vehicle in California?

No, these pistons are not CARB approved and cannot be shipped to California. They are intended for high-performance and racing applications where emissions regulations may differ.

Product Details

If you're building a high-performance 400 small-block Chevy engine, these JE Pistons are a solid choice. They're forged from 2618 aluminum, which gives them the strong tensile strength needed for demanding applications where stock cast pistons just won't cut it. JE Pistons has been making forged pistons for a long time, and these are made entirely in the USA, from forging to machining.

These pistons feature a dome design and are sized for a 4.165-inch bore. They also incorporate JE's proprietary Forged Side Relief (FSR) forging design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power. Some applications also include a skirt coating that further reduces friction and wear, while also quieting down the engine's operation.

This kit includes a set of 8 pistons, complete with the necessary wrist pins. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, especially those intended for racing, these JE Pistons offer a well-built foundation.
