I have the 105A alternator in my 2001 Silverado and I want to upgrade. I tried searching, but only found one link.
So, where else should I look? I'm guessing that the 145A unit from the newer trucks should be sufficient.
What have your experiences been?
I had a Powermaster, it was great. For your application I would either go with a Powermaster or an AC Delco 145, but you might spend as much for a dealer part. My Powermaster was around $150 a few years back, dont know what they are now. I have learned to stay away from Autozone electronic parts. They use little 10 year old Jose in Mexico to rebuild them out in the shed behind the goat pen, and while Jose is a good boy I dont think he has the resources to make a good remanufactured electronic product. Seriously, I have bought starters, alternators and batteries from Autozone, VIP and Pepboys, and have always had failures. I finally smartened up and started buying AC Delco for electronics. The cheap parts places are good for many things, but I stay far away from Jose's remanufactered parts.

Actually the Duralast Gold series of alternators and starters are made near where I live. They are made with all new parts, and are also sold at the high priced auto parts shops under other names.
Duralast Gold is the name of the ones that i have had an enormous amount of problems with. Sorry, due to the lousy quality of the stuff I bought, I just assumed it was made in some third world country. A full warranty is meaningless when you have to take the starter out seven times, not to mention the inconvenience of not having your vehicle start when you need it to. I let them replace it 5 times, counting the stock one thats 6, the 7th starter came off a junkyard truck about twenty years old, never touched it again. Maybe it was just me, or I got a bad batch. After all I only had problems with their alternators 2 or 3 times. I just bought a fuel pump from Autozone yesterday, they didnt have an AC Delco so I got the store brand "Master". What else could I do on a Sunday afternoon? It better be good, it was the same price and warranty as the Delco that they didnt have in stock.
Maybe I'm ignorant to the amount of amp draw but maybe some of you could help me out. ON the new Chevy's and GMC half tons, the plow prep provides a 160 Amp alternator while on the 3/4 ton, the plow prep only provides only 145 Amp Alternator. I think its safe to assum that more 3/4 ton trucks will be used to plow then the half ton trucks. So why would they not try to adapt a version of the 160 amp alternator for the 6.0L and bigger trucks? Seemed like an appropriate time to post the question.
Cork, it may have something to do with the speeds the alternator gets spun at, but that's just a SWAG and I really don't know.
As for my new alternator, it is physically larger than the stock unit, but the wiring looks to be the same and the bolt locations are the same, so I think it'll bolt right in. (Fingers crossed) The fact that it is larger means that it shouldn't be working harder to produce the extra power and its idle output should be good. (At least as far as I understand it.)
I guess we'll see. If it doesn't work the way I think it should then I guess it'll be up for sale.
It probabily has something to do with battery size. The half tons probabily have a significantly smaller battery Or a battery with no reserve time and the 2500's will have a bigger battery. Remember all manufacturer's consider 1500/half ton trucks as cars and 2500/3/4 ton as the smallest commercial truck. (even if they don't advertise it that way they usually design them and market them that way)
Get is also onto something- if you;re talking diesel versus gas the diesel has significantly lower rpm in most cases so the same alt will not normally generate the same current overall.
My replacement (auto parts store rebuild) was marketed as a 120AMP but has the testing cert label on it saying peak of 160AMPs. the stock for my Ram is a 135Amp being diesel and plow prep where the stock gas/non plow is 120.

getmore- I recently purchased a heavy duty 130amp alternator from Napa with a lifetime warranty. It was $285. dollars. I also have a '01 chev.
Well I got the new alternator installed today!
I had to get a new belt, as the stock one for a 105A unit was too short. Other than that it was a direct bolt in.
