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.
- Made in the U.S.A.
