JE Pistons SBC 400 FSR DOME Set of 8 Pistons

This is a set of eight JE Pistons, specifically designed for SBC 400 engines with a 4.130 inch bore. You'll receive the pistons themselves, ready for installation in your performance build. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, a material chosen for its high tensile strength, which is crucial for engines that demand a lot of performance and durability. JE Pistons brings over 75 years of experience to the table, focusing on creating pistons that can handle the rigors of racing, whether that's on the dirt track or the drag strip.

What sets these pistons apart is their proprietary Forged Side Relief (FSR) design. This unique forging minimizes friction and power loss by using a reduced skirt width and a shorter wrist pin, which also helps save weight. Depending on your specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to improve ring seal and keep power consistent. Some applications also include a skirt coating that works to reduce friction and wear on the piston skirts and cylinder walls, leading to quieter operation and longer life. Each piston is engineered specifically for its intended engine and use, ensuring you get optimized performance and durability.

Because these pistons are built for high-demand applications, they are made 100% in the USA. This ensures a high level of quality control throughout the manufacturing process. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds where durability and consistent power delivery are key.
