a few good companies....

excessive amperage, ohio alternator and 4alterstart.

4alterstart 275amp is what I have. Only one to offer a 2 year warranty and slightly cheaper than the others. Not to mention offers the most power at idle too. I've done allot of research. But what I have read from other people, any of the products will do.

my 200A excessive amperage alt puts out over 100A at idle. Not too shabby :)

Ohio alternator has been making high output alternators for at least a decade. They have proven themselves.

But there's no reason the other wont work if they are made right.

Just a question. If you change your alternator to a higher powered one, do you have to add a high powered battery as well. Iwas once told if you change the battery to a bigger and better one the stock alternator won't be able to recharge the battery and therefore causing the battery to die earlier than need be. Is there any truth in this?

No, as long as the battery isn't old. Any fairly new battery will work. There is benefits to having a deep cycle battery.

yes, pretty sure its the same one. Give them a call. You only use 2 of the 3 bolts. Works well, had it for nearly 2 years now. Goes in the same spot. :) No need to relocate or anything.

There is a 200amp version. Not to mention they give you a spec sheet on each one.

Do not get an alternator from Nate of Excessive Amperage. I've been through 3, his shipping sucks, he ripped me off after sending him my last core. Crappy warrenty, etc. Just a bad experience.
