JE Pistons 400 SBC .175 DOME Set of 8 Pistons

This is a set of eight forged pistons from JE Pistons, specifically designed for a 400 SBC engine with a 4.155 inch bore. You get the pistons themselves, ready to be installed in your engine build. These pistons feature a .175 dome and are made from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that demand a lot of performance. JE Pistons has been making forged racing pistons for over 75 years, and they engineer, forge, and machine these right here in the USA.

What sets these pistons apart is their construction. They use a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by using a reduced skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, improving ring seal and keeping power consistent. A skirt coating, also application-dependent, is used to reduce friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation. Every piston is designed specifically for the engine and its intended use, aiming for optimized performance and durability.

Because these are forged from 2618 aluminum and built with advanced designs, they are well-suited for high-demand performance applications, whether you're on the dirt track or the drag strip. 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 output are key.
