Powermaster High-Amp Alternators

13.5V-18.5Vin a 160a alternator case, black powdercoated, XS Volt (Adjustable Regulator 13.5V-18.5V), 5.46" bolt pattern, 1 Wire Capable, 6 Groove Serpentine pulley included, Secondary ground cable stud.

Adjustable Regulator works perfect for applications with larger alternator pulleys needing to up amps at idle without overspinning the alternator. (DO NOT EXCEED 18,000 ALTERNATOR SHAFT RPM) A fully charged battery is at least 12.6V, not 12.0V. A weak/defective battery will cause premature failure.


With modern automotive accessories, such as audio/video equipment, navigation systems, aftermarket lights, and other electrical components, the need for higher amperage alternators has increased. Powermaster has responded to this need with these high-amp alternators. 

Powermaster high-amp alternators feature:

* High output with excellent idle performance
* Hand-wound, custom-designed stators
* Heavy-duty regulators and rectifiers
* Gold plated battery post for better electrical connections
* Proof of performance tags



Powermaster warrants its products to be free from defects in material and workmanship for one year from the date of purchase. Products used for racing and car audio competition are only warranted up to the time of installation to be free from defects. No warranty exists after installation.
