Differences between early (99-02/03) and up trucks

I have converted 8 of these trucks to e fans and used the AD244. I have never had the oe shorter belt fit and it always maxes out the tensioner trying too. If you buy some shitty belt that stretches in could see it but any good quality one won't. So saying you can reuse it... well there is a pretty good chance you won't be.
We've had different experiences, it's cool. I'm not saying you're wrong, I'm sure you couldn't get the belt to work. I did. No biggie.

On the trucks, I can't remember for sure since I haven't done one in a while but I don't think any of the belts were new when I did the 145. None were cheap junk belts though, we don't put cheap junk belts on. It's possible the belt was stretched a little and that helped. I'll have to try the new short belt on the 145 amp some day just for *****. I prefer the short though, so I always use it. Helps when you have high revs and fast shifts.

I shortened my post so it's easier to understand and took out all the talk about the F body stuff, seems you're missing that I mentioned several times that I did it on trucks too.

You can reuse the shorter belt if you want. I've done it several times on trucks and F bodys. I like reusing it because it helps keep the belt on (more tension). I had a F body that tossed the belt all the time on the 1-2 shift or it would at least squeal. After putting on a 145 amp alt it stopped doing it since the belt was tighter.
But here's what I got out of this:

Any alternator bigger than the 105 amp is the large case, and needs the longer belt. I know I bought a 160amp alt at autozone, then later a 300amp for the stereo. The fans from the 07-13 is the superseded part number for the 05-06. The 7-13 fans use smaller blades, (and a I think its two more), about 5-10 more amps (20/25 - 30/35), so they could be designed to be a little quieter. You might then want the 160 amp alternator (although you may not need it). Should make it easier to find a better price by expanding the search if you haven't got them yet.
You're the first person that I've read about that reuses the belt, and hasn't had a problem. This causes squealing on the tensioner and extra drag on every other person I've read about who didn't know to change the belt. This caused them to have voltage problems, but somehow yours seemed to work fine. Any idea how much your belt is stretching before its time for you to do an E-fan conversion? New radiator, fans, coolant, and a tune, and you skimp on a new $20 belt?
But here's what I got out of this:
You were "throwing a belt all the time", and your solution "was to change the alternator".... That's all I needed to hear.

I put a 145 amp on my truck, I was curious if the belt it had would fit, it did so I ran it. I drove it from july of 2012 to january of 2018 like that and it was 100% flawless. Never had a belt issue on that truck, I put 111k miles on it like that. Never replaced the belt or tensioner etc.
Same with my camaro. Put a 145 amp on it, reused the stock belt, drove it from late 2009 to mid 2012 and was flawless, zero belt or alternator issues after putting the 145 on it. I have a 50 page thread on ls1tech where I showed guys what to do to put a 145 on F bodies, they all reused the belt when it "needed" a longer one and nobody has reported any issues.
