Just wondering if anyone knows if there are any bolt on alts. that put out higher amps the our 105 amps stock ones.

i realized there are high output one but they are very costly and not relible.

the 3.4 van's ( montana) from what i hear have 120-125 amp alt's

anyone no if they bolt right on?

Look around your area there has to be a local shop that can build you one, that way if it fails, you won't have to deal with shipping and stuff. I found a guy 5 miles from my work who will build me a 180 amp for 200 bucks or a 150 amp for 160 bucks.
