02 Yukon 1500 alternator recommendation

I bought a 02 Yukon xl 1500 with the 5.3 and the alternator has gone bad. I plan to install dual batteries in it. Is there a specific alternator I should buy to support 2 batteries or is the stock 130 amp OK?

yes, but since you are replacing it anyway it doesn't cost much more to get the higher capacity models. Add more than you need so you have so there's room for expansion later. If you have any big lighting or electronics ideas going forward.

Autozone lists both 105A and 130A alts for the same price. And 145A is only $10 more.
