Alternator GENERAL MOTORS or Duralast

The OEM alternator is only 55 amps and costs nearly $400, which is stupid expensive and wholly inadequate for off-road lighting, audio amplifiers, and other additional accessories so I decided to go with the CS130D GM alternator, purchased for under $100 new (no core charge) and has a 130 amp capacity.

I'm getting 14.8v from the upgraded alternator at 700rpm and maintaining 14.2v when every possible accessory and light is turned on at idle.

For hpw old your car is, and the price of these boys in the photo, id go to your local autozone and get their alternator, simply because they come with a lifetime warranty

I'd just get something with a warranty. I've been using Duralast from Autozone for the longest time and haven't had too many issues

Just bought and installed a Duralast Gold from Autozone last week for my '07 9-5. It has a little whine at 2500 RPM but works better than OEM. Has a lifetime warranty and it's 100% new too!

I’ve never had an issue with a Duralast starter or alternator. However, honestly, I probably wouldn’t put one on my Lexus. I’ve generally shoved them into cheaper and simpler cars.

Autozone will give lifetime warranty on certain (duralast gold maybe?) alternators. I got the replacement very wet (dumb), and it died while I was driving.

I burned up 4 of the duralast Gold GM 12si alternators while they were still under warranty, if I had to venture a guess it would be they don't like high RPM . I removed them from two of my samurai's and went back to stock, haven't had a problem since

I went through 3 duralast nators on my wife's exploder before I got one that lasted more than 6mos. Aftermarket everything has mostly gone to shit.

I have experience with both shitty Autozone Duralast alternators and I would not purchase them.

I have shadow codes for my water pump because of it, and my voltage is not high enough at idle, and never surpasses 13.5ish volts. It whines loudly, and it doesn't make the same power as my last alternator contrary to the ratings.

The refurbished Duralast alternator has worked fine for a few months but the last month I started to hear belt noise and assumed it was related to the alternator. The last couple of weeks I would smell a new unknown burnt smell that smoked like either rubber or electronics which has led me to wonder if the battery/alternator fuses have gone out.
