ARCO Marine Zeus A275L J-180 4" Alternator w/Terminal Block [4022]

Zeus A275L J-180 4" 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.
  • 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.
