Description

This piston kit is designed to maximize the performance of Ford Flathead engines. Engineered, forged, and machined in the USA from 2618 aluminum for high tensile strength, ideal for racing applications. Features include Proprietary Forged Side Relief (FSR) for minimized friction and a lighter assembly, and skirt coating (application-dependent) to reduce friction and wear. An accumulator groove helps manage combustion gases for enhanced ring seal.
