Why run multiple alternators?

What if you had a separate charging system dedicated to the additional accessory load? By running multiple alternators you can do just such a thing, and doing so leaves the factory charging system intact doing what it was intended to do, running the vehicle while the secondary alternator carries the additional accessory load. By effectively doubling the available amperage of the vehicle, you can run more accessories with less worry, and all for about the same cost as a single high quality High Output alternator. Whether you have an EMS, Fire Truck, Paramedic, Police and SWAT vehicles, Shuttle Buses, Car audio, Military and Homeland security we have your back. We are very proud to say, our multiple alternator kits are 100% designed and manufactured in the USA!
