The Bosch 125 amp should be a direct swap.

I bought a new KG7 (125 amp option) alternator on Rockauto a few months ago when mine crapped the bed...I think it was only about $120 for a TYC with a LLT warranty.

It's not quite a direct fit...you need an aluminum spacer. Rockauto has it as part number 24508156 for $6.24.

So the slight increase in amps will be fine? I've been looking into alternators for a while now, but wasn't sure if the 125 amp would work.

Using a larger alternator is OK. The system only takes what it needs. It's not like plugging a 110 volt device into a wall socket that has 220 volts. There is a local starter/alternator shop that takes the customer's 100 amp alternator, & replaces the guts to supply 180 amps to run hi power stereo's the owner installs in the car. This way, the upgraded alternator still fits in the car, as the case is still the original size. GARY

I'll second Gary by saying this...I used my original 125 amp from my 2001 L36 9C1 when I swapped the 2005 L67 engine and tranny in. I just needed the alternator and the spacer. No problems whatsoever.

Alright then. Just wanted clarification. I know people on here using 200 amps and needing some kind of extra fuse to run it. Puts my worried to rest. Very Happy

it's possible all you need is a 240/250v to 120v adapter.


since here it's a split phase (4 wire) two hot, one neutral and one ground.
120v lines(20-40amps) which only the 120v uses one hot one neutral and one ground .


outside the USA I think it's just a straight 220/240v (440/480v split phase) for the hot wire.

under worst case scenario the stock wires is a poor choice for a 200amp alternator. yes a in line fuse should be used for the AWG used or install larger wires

Wondering... does anyone make the 125a NEW.. not reman like those two? I know they go through this whole process to make them 'like new' and yadda yadda... I'm just wondering is all.

I recently swapped out an alt. on a 3.1 J-body and it had a Delco reman in it that did go a good distance time-wise before the regulator quit functioning... I replaced it w/a bran-new Delco that I had to pick off Amazon and wait for.

Most alternators/starters sold by AC Delco are reman, even if for a 2014 model car. Every now & then they offer a brand new unit, but that is rare. You also have to be aware what the box says, "Reman by GM, vs Reman for GM". Big difference. GARY

I'd have to look at the box, but it was new "AC Delco" made in Mexico, as it says on the casing. Old one stated "Delco-Remy" on the casing.

Car Quest, Napa, etc may offer a 'new' 125a alternator,... but I would trust a reman Delco long before I trusted a parts store brand. And like 9C3 hit on,.. almost any Delco alternator or starter will be reman. New ones are usually oddball OEM ones made by Mitsubishi or something. Laughing

The TYC ones Rockauto sells for $120ish are new.
