CHEVROLET 400 -7CC DISH 1.425 X 4.1

This JE Pistons Ford 4.6L Modular 4V FSR Piston Kit is designed for high-performance domestic applications. Forged in the USA from 2618 aluminum, these pistons offer high tensile strength. The proprietary Forged Side Relief (FSR) design minimizes friction and power loss through reduced skirt width and a shorter wrist pin, contributing to weight savings. Depending on the application, features like skirt coating can reduce friction and wear on both piston skirts and cylinder walls, while an accumulator groove helps improve ring seal for consistent power by reducing pressure from combustion gases. This kit is engineered for specific engine and use applications to optimize performance and durability.
