Zeus A275L Vortec Alternator with Terminal Block
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.
