Chirco Performance offers many types of high output alternators for your performance VW dune buggy or VW sand rail. We offer the 90 amp alternator that is made in the USA and is a top quality alternator made specifically for a performance build. We also offer the USA made 90 amp alternator that has a cooling fan installed. This comes in handy when you have accessories that will require extra power. If you're looking to dress things up a bit, we also have the polished aluminum 90amp 12V alternator. Don't have an alternator for your sandrail and you're sick of the generator that you have? Look into our alternator conversion kits. Our two types of kits are the standard conversion into the 55 AMP alternator, and then a chrome conversion kit that is also into the 55 AMP alternator. If you have any questions regarding your alternator, please feel free to give us a call at 1-800-955-9795 and we will get you taken care of.
