JE Pistons SBC 400 FSR DOME Set of 8 Pistons

If you're building a high-performance Small Block Chevy 400, these JE Pistons FSR Dome pistons are a solid choice. JE Pistons has been making forged pistons for decades, and they build these right here in the USA using 2618 aluminum. This material gives them the high tensile strength you need when you're pushing an engine hard, whether that's on the drag strip or a dirt track.

What sets these apart is the FSR forging design. It's a proprietary design that JE uses to reduce friction and power loss by using a narrower skirt and a shorter wrist pin. This also helps save weight, which is always a plus in a performance build. Depending on the specific application, these pistons might also come with an accumulator groove to help control combustion gas pressure, leading to better ring seal and more consistent power. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet things down a bit. These are designed specifically for the SBC 400 engine, ensuring optimized performance and durability for your build.

This set includes eight pistons, each with a 4.155-inch bore and a dome shape with a 10.8 cc volume. The wrist pin is 0.927 inches. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for high-demand performance applications, so they're a great way to equip your engine with proven forged piston technology.
