Question Mean Green Alternators?

Hey has anyone heard of these guys? Im in the market for a high output alternator and stumbled across this site. Apparently, they are direct replacements. $399 seems steep though.

I was also curious, do 100amp + alternators add more strain to the rotating mass of an engine than a standard alternator?

It looks like they're available for most of our trucks.

Saw a thing about them awhile back... I think someone here looked at them or maybe even got one I don't recall... You'd have to go through all the high output alt. threads to find it... try a search...

as for extra strain not really... the only time you might notice it was if you put a huge elec. load on the system you might see a slight rpm drop but it would not add any "strain" on anything... by going with a higher "normal" output alt. compared to the stock alt. you might not even see this.
The HO alt will be heavier than the stock one so you would be carrying more weight around but you'd never notice it (as long as you don't drop it on your foot while installing it that is ) from an MPG/performance pt. of view...

You can get the alt bracket from LC engineering or Trail gear

Trail gear just had a sale on them for $29

Sadly no one seems to make brackets for the 3.0 to take a GM alt.

I guess it's still possible to do the swap. I've been searching through some threads and noticed people using spacers to line up the pulleys (hopefully the spacers to add too much stress to the longer bolt when wheeling hard). Then extending the lower bracket somehow(?) to use the tensioner. It's double the size of the stock 3vze alternator so thay could be a issue too.

Just FYI, I found some numbers. However, the power loss is very small.

746watts = 62.2amps = 1hp

140amp alternator at full output will drain 2.25hp. And 180amp = 2.89hp


There's also another company based in socal that builds alternators. They say their 180amp small body is a direct fitment and as small as our stock units. It also puts out 120amps at idle! Cost is $400 and you'll have to call them if you have a 2nd Gen. They're not shown on the site.
