ARCO Marine Zeus A275L 1"-2" Single Foot Alternator with Regulator - Part #4029

Zeus A275L 1"-2" Single Foot 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. 


• Runs 8 - 20% cooler than incumbent alternators due to Heat shedding coatings, Rectifier located on 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.
