Zeus A275L Vortec 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.
Use an ARCO Zeus Bluetooth alternator regulator or lithium battery charging for maximum performance.
SAE J1171 Certified.
