JE Pistons 400 SBC PRO ACTION Set of 8 Pistons

This is a set of eight JE Pistons PRO ACTION pistons, designed for a 400 SBC engine. You get the pistons themselves, ready for installation. 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 exactly what you need when you're pushing an engine hard. JE Pistons has been in the game for over 75 years, and they've put that experience into making pistons that hold up under tough conditions, whether you're on the dirt track or the drag strip.

What sets these apart is the attention to detail in their design. They feature JE's proprietary Forged Side Relief (FSR) forging design, which helps cut down on friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to keep the rings seated properly for consistent power. Some applications also include a skirt coating that further reduces friction and wear, making the engine run quieter and last longer.

Because these pistons are designed specifically for the 400 SBC engine and its intended use, you can expect optimized performance and durability. They are made 100% in the USA, ensuring a high level of manufacturing control. Keep in mind these are not CARB approved and cannot be shipped to California. For a high-demand performance build, these pistons are a solid option.
