At Chirco, we provide top of the line VW dune buggy alternators and generators. We carry a 12V 51 amp alternator and a 12V 30 amp generator. The generator is a brand new Bosch brand, which is a top of the line brand. However, if you are replacing your generator, it may be in your best interest to replace the voltage regulator as well. The beauty about our 12V alternator is that it is brand new and there is absolutely no core needed. While you're in there replacing the alternator or generator, take a look at the alternator or generator stand. These stands are available in a stock type or if you are wanting to dress up your engine a bit more you can get the chrome alternator or generator stand. The alternator or generator strap, pulley and others are great things to replace all at one time. It ensures that all pieces are in perfect condition. If you have any questions with your alternator or generator, please don't hesitate to reach out to one of our associates at 1-800-955-9795 and they will assist you with all of your questions.
