Description

Zeus A275L 1″-2″ Single Foot 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.
• It is optimized for performance at idle speeds.
• Reduces the need for a generator by creating additional power with your engine.
