Just by adding a few electrical accessories such as driving lights, auxiliary cooling fans, or a mega-sound system you can quickly exceed the capacity of your Jeep alternator. POWERMASTER has the solution - high output alternators that bolt in place of the OEM alternator. They feature a slightly larger case that bolts to all factory brackets and use the same belt. POWERMASTER has reengineered the power curve to deliver up to 50% more output at idle. Every POWERMASTER high output alternator is tested and comes with a proof of performance tag.
