Zeus A275L J-180 4 Alternator with Regulator

The highest power output alternator in its size/class.

Features:

• Engineered for High Energy Production.


• Suitable for Marine, RV, Military, and Commercial applications.


• Rapidly charges large battery banks.


• Coolest operating temperatures for increased performance.


• It runs 8 - 20% cooler than incumbent alternators due to heat-shedding coatings, a refrigerator on the housing exterior, dual cooling fans, and OEM components.


• It is optimized for performance at idle speeds.


• Reduces the need for a generator by creating additional power with your engine.


• Unleash peak performance with E-Coat/Cerakote. Our advanced coating absorbs less heat, keeping the A275L cooler. This translates to more amperage for sustained periods.
