TYC heavy-duty alternators are built brand-new, with no recycled internal components. The bearings, field casing, rotor, rectifier, stator, diode, regulator are all 100 percentage new; not remanufactured. As such, there is no core charge where you have to return your old part to the store to get your money back. 100 percentage new with no recycled or remanufactured components means that your TYC alternator is factory-fresh, and unused by any other vehicle. This improves its reliability over longer periods of time, ensuring that you do not have to find another replacement for the foreseeable future. New TYC alternators are designed specifically for your vehicle and are ready to be installed quickly and easily for a perfect match. Remove, install and go, with minimum downtime for your vehicle.
