JE Pistons 400-18 SBC FLAT TOP Set of 8 Pistons

Forged in the USA from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is specifically designed for SBC (Small Block Chevrolet) engines with a 4.155-inch bore, featuring a flat-top design with a -6.00 cc volume. The 2618 aluminum alloy provides the high tensile strength needed to withstand the rigors of performance builds, ensuring durability when you push your engine hard.

JE Pistons incorporates several advanced design features to optimize performance and longevity. The proprietary Forged Side Relief (FSR) forging design helps minimize friction and power loss by reducing skirt width, while also saving weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, which helps prevent ring flutter and improves ring seal for consistent power delivery. Additionally, 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 set includes eight pistons, all manufactured and machined 100% in the USA. They are designed specifically for each engine and use application, aiming for optimized performance and durability. Please note that this part is not CARB approved and cannot be shipped to California. It is important to check manufacturer fitment data to confirm compatibility with your specific engine build.
