I got in on my 06 just to charge my batteries quicker as I have a rather short drive to work... Plus helps with the stereo eq that I am running.

Wish i got mine. Will need them next winter. Plow relays drain voltage down to 9volts when in constant use. Dual altenators def. a must for plowing.

I think for most of us they are not really necessary. For me it was a "Why the he!! Not" decision. The little order form box was there and it wanted me to check it.):h

It is nice to know there is an extra one, But it could be viewed as just another thing that will eventually need to be replaced.

Think it is a great option if you put a plow on.

dual altenators

What was the output of the altenators both single and duel? They had them some years ago for emergency vehicles and such. If you are running a highter load then it could be for you. Wondering when they will have AC power for high power loads and DC for low power loads??? It would be better then highter voltage DC for most things.

The single alt. is 145 amp.The duals are 105 amps each.

I ordered the dual alternators to help in charging the batteries in our 5'er when we're running down the road. Lot's of juice needed at night with all the running lights burning. There's a pic of them in my garage.


Truck on!!!:cool:

You can add another alternator later, but the factory option is a lot less expensive. It's also less expensive to upgrade one or both 105amp alternators (if you need to) than adding a second alternator to the standard 145amp single alt.

Unless you have a whole bunch of other 12v accessories in the truck, you really won't need the duals. As long as you have the plow prep package w/the 145amp alt., you'll be all set. What kind of plow?

i had the 145 amp with my western plow and that baby still dropped like a rock voltage wise. I switched to dual 105's and my guage bearly moves when i go plow up. I put the 145 on my gasser for a little help there. But my diesel has the duals and it also helps cuz i like lights and stereo's and air horns n such.

Thanks for the info, but you didn't really answer my question. Can dual alternators be put on the gasser or are the belts and such different?

Really, you had trouble with the single 145 and your plow? I have the 145 on my truck with a Fisher blade on there and I just got back from a long day/night of plowing with no trouble at all. The voltage meter would drop a little bit when using the plow a lot, but it wasn't an issue at all. As soon as I let of the joystick, it went right back up.

You don't need Duels alternators for plowing. I have electric salter, electric plow and electric host on my mason dump I never had problems with power. Even with a gas truck with the same set up duel batteries and one 105 amp alternator no problems with power.

The problem comes from all the accessories tacked on the side mount batterys all those connections are prone to loosen from all the weight and build up with corrosion.

Short answer is no. The D'Max has a spot for the second alt. all you need is an alt, addon bracket, belt etc. The gassers don't have that spot set aside for the duals, aftermarket may have something though.
