Pistons, Single - 400-18 SBC FLAT TOP

JE Pistons offers 400 small block 18-degree flat top pistons for a wide range of applications, including many Chevy vehicles from 1967 and up. These single replacements are forged using 2618 aluminum, yielding high tensile strength needed for high-demand performance. The pistons are designed specifically for each engine.

Additional details:
• Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
• Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
• Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
