Has anyone upgraded from the 150 amp (rpo KG4) to the factory 170 amp alternator (rpo KW7) or the 220 amp (KW5)?

I believe my 2018 Prem came with the 220A and when that died I swapped in a 270A. Not sure if that helps?

You have the 6.2 or the 5.3? By any chance do you have the part number for the 270?
