*Attention!* This is a Computer-Controlled Charging System
- This vehicle uses a factory computer (ECU/PCM) to control charging voltage, so voltage will continue to follow the factory system behavior.
- This high-output alternator still provides the increased amperage you purchased, delivering stronger performance under load and faster battery recharge
- Custom or fixed voltage output will require ECU tuning.
This alternator comes with a similar sized pulley as factory so you are able to reuse your stock sized belt if it has less than 50K miles on it along with the tensioner. This is a plug and play alternator for factory vehicles. If you are needing this for an engine swap application, please see our engine swap section for an easy 1 wire 12v switched source operation.
