BorgWarner's Delco Remy 55SI is designed to take on the electrical loads of heavy-duty vehicles from 12V utility and work trucks to 24V wheel loaders, graders and mining equipment applications.

  • 12V, 430 Amp; 24V, 250 and 275 Amp models provide high output performance at engine idle
  • Brushless design has fewer moving parts, less wear and longer life
  • Battery charge time can be reduced by 50% through Remote Sense, which utilizes a second wire that reads the actual voltage at the battery and signals the alternator to boost its output to compensate for the voltage drop, ensuring 14V at the battery
  • Weighs 43 lbs.
  • Frame length is 8 in., freeing up engine mounting space
