Are all aftermarket alternators crap? Hey everyone,
After doing a bunch of research on this forum and some others, it seems like most aftermarket/rebuilt alternators for the LS1 are pretty crappy. Mine pooped out about a week or two ago, which as far as I know has about 80,000 miles on it. I was looking at the Powermaster units which, while expensive, seem to be a safe bet. My question is, do I have any options beyond the trial & error auto parts store units (advance, autozone, etc.)? Is it worth it to get my current one rebuilt locally? Is the Powermaster unit a direct bolt-in (no mods needed)? Thanks for your help.

I've had two aftermarket high(er) output alternators - one crapped out on me with no warning after about a year of use, the other is still going strong. The one that crapped out came from Afterthoughts Auto (they subcontract it out to someone else), and the one that is still going strong was from Alterstart.
Hit and miss with this one...especially if you are going for more output than stock.

All stock electronics in the car except for the Raptor shift light, so I'm not concerned about get a super high-output unit. Getting one with a lifetime warranty would be good, but if it craps out every 6 months or so, that's a lot walking home I'll be doing. When my last one went, man, it WENT. Gave me about 10 minutes to get my *** home and the thing died as I rolled into the driveway. I'll take a look into the Pro Starts. Anyone have the Powermasters?
