JE Pistons SBC 400 FSR DOME Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons are built for serious performance in your SBC 400 engine. This set of eight pistons features a dome design and JE's proprietary Forged Side Relief (FSR) forging. The FSR design is key here; it reduces skirt width to minimize friction and power loss, while also saving weight with a shorter wrist pin. This attention to detail means you're getting a well-built component that's optimized for durability and performance, whether you're on the dirt track or the drag strip.

JE Pistons has been a leader in forged racing pistons for over 75 years, and they machine these entirely in the USA. The 2618 aluminum alloy provides the high tensile strength needed for demanding applications. Depending on your specific engine setup, these pistons may also include an accumulator groove to help control combustion gas pressure, leading to better ring seal and consistent power. Some applications also benefit from a skirt coating that further reduces friction and wear, quiets operation, and helps protect your cylinder walls.

This kit is designed specifically for the SBC 400 engine, with a 4.185-inch bore and a 10.8 cc dome volume. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in their V8, this set represents a solid choice backed by decades of racing experience.
