JE Pistons 400 SBC DOME -12 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 4.125-inch bore and a dome piston design with a -12cc volume, intended to work with specific cylinder head chamber volumes for optimal compression. The use of 2618 aluminum alloy provides the high tensile strength necessary for the stresses of performance engines.

JE Pistons incorporates several design features to enhance durability and performance. The proprietary Forged Side Relief (FSR) forging design helps minimize friction and power loss by reducing skirt width, and further saves weight with a shorter wrist pin. Depending on the specific application, an accumulator groove can be included to reduce pressure from combustion gases, which helps prevent ring flutter and improves ring seal for consistent power delivery. Some applications also feature a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life.

This piston set is engineered and machined 100% in the USA, reflecting JE Pistons' extensive experience in creating high-performance engine components. Each piston is designed for the specific engine and intended use, aiming for an optimized balance of performance and durability. Please note that this part is not CARB approved and cannot be shipped to California.
