Product Details

Forged from 2618 aluminum, these JE Pistons are built for serious performance in your 400 SBC engine. This set includes eight pistons, each featuring a .500-inch dome and a 4.155-inch bore, designed to handle the rigors of high-demand applications. JE Pistons has been a leader in forged racing pistons for over 75 years, and this set reflects that experience, offering a robust combination of durability and optimized performance for your build.

JE Pistons applies advanced design principles to each specific engine and application. This set utilizes a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing 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 reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

Every component in this piston set is forged and machined 100% in the USA, ensuring a high level of quality control and supporting domestic manufacturing. The 2618 aluminum alloy provides the high tensile strength necessary for demanding performance engines, whether you're building for the drag strip, dirt track, or any high-performance street application. This kit is designed to provide optimized performance and durability, making it a solid choice for engine builders looking for proven results.
