JE Pistons 400 SBC DOME 18DEG Set of 8 Pistons

Forged in the USA using 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is specifically designed for the 400 SBC engine, featuring a dome shape and an 18-degree piston angle, with a 4.145-inch bore. The 2618 aluminum alloy provides the high tensile strength needed to withstand the rigors of performance engines, ensuring durability alongside power.

JE Pistons applies over 75 years of experience to their forged racing pistons, and this set is no exception. They incorporate a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. Depending on the specific application, these pistons may also feature 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.

This piston kit is designed for optimal performance and durability, engineered specifically for the 400 SBC engine and its intended use. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure you check all manufacturer installation instructions before beginning your build.
