Modern accessories can take their toll on a vehicle's electrical system. Powermaster offers High Amperage Alternators to give your electrical system the extra boost it needs. If you have added lights, winches, or other power hungry accessories, Powermaster offers easy to install high amp upgrades.
Note that the alternator comes with a single-groove pulley. If you have a double-groove pulley, you will need to change them over (they are a direct swap). Also, if you have an older model vehicle with an external voltage regulator, you can use this alternator with some minor wiring changes under the hood. This will allow you to remove the external regulator and associated wiring too!
