I wanted to know if there is a bigger alternator out there that will fit on the 02 envoy? I am running 4 batteries in the back on isolators and wanted to know if i could beef up my altern aternator?

They make a 205 amp version of the alternator on the TB's... Contact these guys about upgrading a 4.2 case (they are block mount, vice swing mount).
