Arco Marine Zeus A275L J-180 4-Inch Alternator with Built-In Voltage Regulator (4024)

Description

Zeus A275L J-180 4″ 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. 
• It runs 8 – 20% cooler than incumbent alternators due to heat-shedding coatings, a refrigerator on the 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.
