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 engine applications.

Are these pistons compatible with all 400 Small Block Chevy engines?

This set is designed for 400 SBC engines with a 4.145 inch bore and 18-degree valve angle compatibility. It's always best to verify the specific requirements of your engine build against the piston specifications.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary JE Pistons feature 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.

Product Details

If you're building a high-performance 400 Small Block Chevy engine, a solid set of pistons is crucial for handling the power and stress. These JE Pistons are designed specifically for that kind of demanding application, giving you a strong foundation for your build. They're made from 2618 aluminum, which is known for its high tensile strength, making it well-suited for engines that will be pushed hard.

JE Pistons has been in the game for a long time, and they build these right here in the USA. They use a proprietary Forged Side Relief (FSR) design that helps cut down on friction and weight by using a shorter wrist pin and reduced skirt width. Some applications also include an accumulator groove, which can help reduce combustion gas pressure, leading to better ring seal and more consistent power delivery. If your application includes a skirt coating, that's an added bonus for reducing friction and wear on the cylinder walls, which also helps quiet things down a bit.

This set includes eight pistons, each with a dome design and an 18-degree valve angle compatibility, a 4.145-inch bore, and a 0.927-inch pin. Keep in mind these are not CARB approved and cannot be shipped to California. For a serious engine build, these pistons offer a well-built option with a lot of proven performance behind them.
