Alternator swap info

[CdnDenali]

Looking to upgrade/swap my 130amp alternator for a higher output unit. Cant seem to find any info. Not wanting to go aftermarket. From what I have gathered so far is, the biggest I can go is 160amp and they are found on the 2001-2006 HD's and belt replacement (bit longer belt), strait plug and play?? Any comments or advise is welcome

Contact excessive amperage for your alternator needs. I have four 350s alts from them.they can make you whatever size you want.

Lol just read your post about not wanting to go after market. Carry on

Edit: life time warranty on excessive amperage FYI

I swapped in a 160 amp into my 03 Tahoe a few months ago. Originally had the 130 amp. Straight plug and play. Used the same belt. No modifications needed.

Are those 160amp only found on Special Service Vehicles? Thought I read somewhere, an alternator out of a HD 2500 was plug and play but with a different belt size.

My '05 Denali with a 6.0L came from the factory with a 160amp. As far as I know I have the same LQ4 engine that was installed in the HD 2500s.
