The bearings, field casing, rotor, rectifier, stator, diode, regulator are all 100 percent new and not remanufactured. 100 percent new with no recycled or remanufactured components means that the TYC alternator is factory-fresh, and unused by any other vehicle. This improves its reliability over longer periods of time. New TYC alternators are designed specifically for your vehicle and are ready to be installed quickly and easily for a perfect match.
