    I have a 2000 1500 Z71 with a 105 amp alternator. I would like to get a 145 amp or 160 amp .. Can I get one from a 03+.. I have the 5.3L..

    Thanks in advance

    As long as the pulley, mounts and housing are the same, it should swap right in.

    I would rather not buy one and then find out it doesn't fit...

    Napa probably has a High Output Alternator for your truck. You will want the big charging kit. Put one in my 97, made a big difference.

    Try Mean Green, they sell one specifically made for your platform. They have a couple different AMP output options.
    Also try looking at local alternator rebuilders, a lot of times they know ways to squeeze a few more amps out of a stock alternator.

    you could even get one like mine on my police package 99 tahoe that is 240 amp if you like, it should work too. the only thing you'll need to make sure of is that the bolts clear touching anything metal on the back side of the alternator. what do you need a higher output alternator for and how many watts are you trying to push? may be something you can resolve with a good sized stifffening capacitor
