JE Pistons 400 SBC .305 DOME Set of 8 Pistons

This is a set of eight JE Pistons, specifically designed for a 400 SBC engine with a .305 dome. You get the pistons themselves, ready to be installed in your build. These aren't just any pistons; they're forged from 2618 aluminum, a material known for its high tensile strength, which is exactly what you need when you're pushing an engine hard. JE Pistons has been in the game for over 75 years, and they build these right here in the USA, tailoring them for specific engines and racing uses to give you a solid combination of durability and performance.

What sets these apart is JE's proprietary Forged Side Relief (FSR) design. This means they've worked to minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also helps shave off some weight. Depending on your specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to keep your rings seated properly and maintain consistent power. Some applications also feature a skirt coating that's designed to reduce friction and wear on the piston skirts and cylinder walls, leading to quieter operation and longer life.

When you're building a high-performance engine, especially for demanding applications like dirt track or drag racing, you want components you can trust. These pistons are made 100% in the USA, ensuring you're getting a well-built part designed for serious use. Keep in mind that these are not CARB approved and cannot be shipped to California. You'll also want to check the manufacturer's installation instructions for details on pin fitment and any specific requirements for your build.
