I am thinking about building an on board air system for my truck. I am going to order a set of Air Lift 1000s for my rear springs. (I have an '09 Ram with coils in the rear).

The air bags inside the coils should be pretty straight forward. The on board air is something that I have never messed with.

Here are the Air lift 1000s,

I dont know what kind of amperage my charging system can handle. I dont want the compressor to cause any electrical problems.

What do you guys think?
