Any surfaces that your Ford turbocharger require to be refinished/squared are performed on our In-House CNC machines. All of our Ford Powerstroke turbochargers are rebuilt using components that are at or above OEM quality. All of Pro Systems Powerstroke turbochargers are Dual Plane Digitally/Computer balanced to ensure smooth operation and long life.
