These pistons feature a -5.40 cc dish, which helps manage compression ratios in performance builds. The inclusion of a specialized skirt coating is critical for high-performance engines, as it minimizes friction and prevents scuffing during the break-in process and under high-heat conditions. By choosing forged over cast, you are ensuring that your engine can handle the heat and pressure of aggressive driving. These pistons are the foundation of a reliable, high-horsepower engine build.
