100% New. This SR Performance 150 Amp Mustang Alternator is 100% brand new, not re-manufactured like other companies sell and is fully tested at the time of assembly. It comes complete with internal voltage regulator and 6 groove pulley. The 150 Amp alternator will increase the charging capacity at all RPM Ranges with no modifications required.

More Power. The SR Performance Alternator produces 65 amps at idle (1750 alternator shaft RPM), and 150 amps at maximum.

Peace of Mind. Why waste your time and money rebuilding your alternator again and again when it will only fail, replace it with a brand new high performance alternator from SR Performance for peace of mind.

Is power wire upgrade needed? Is this a direct plug and play swap? Will it work without upgrading the power wire? Also is this higher output than stock?

  • Since it states in the description: Application. The SR Performance 6G Series Alternator is a direct fit replacement with no mounting bracket modifications required to be installed in a 2005-2008 GT Mustang. The stock belt can be used on original equipment vehicles. I would say it is a direct plug and play swap and I believe stock factory alternators are rated at 135 amps, so yes it has a higher output.

    Loud, loud, loud

    Got the alternator today and installed it no problem. Once I started the car the thing was loud. If you can deal with a loud whining alternator than this item is good but I would not order again. Hopefully it goes away once broken in.

    Excellent replacement!

    Had the infamous code problem, it even started shaking while on throttle and turning on electrical stuff as simple as the directional or the high beams, so I got this installed in about 2 hours (first time doing this) and done! The code is gone and hasn't come back, the car even feels smoother, and once I was installing this, took the liberty to clean the throttle body and the MAF sensor so all in all, great afternoon for my pony! Thanks AM!

    No change

    This alternator came in a box labeled 135 amp. This alternator was tested and put out 135 amps. Still have a stock alternator on the car when I ordered a larger one. Was easy to install took about an hour to take old one off put new one on and install new belt and clean throttle body. Fits like stock because it is the same thing.

    Great Product!

    This alternator is fantastic! Side by side with my old stock alternator you can tell that this one is of much higher quality. Product came on time and looked awesome upon arrival. Installation took me about 30-45 minutes, do to the fact there was not enough clearance to swing the old alternator out from under the throttle body, so the TB had to be removed. I would have gave 5 stars to the performance gain, but really it's an alternator and there isn't really any noticeable performance. As always AM pulls through for me again! Great job, great product love these guys!

    P0340 code gone

    Had the dreaded cam sensor code, did everything nothing worked until forums said its the alternator. Replaced, now its gone. Think my old one was robbing power from the car. Ran 13.3 before ran 13.11 after in my auto. Can't say you'll have same results but track the car alot. Its consistent, only thing I dont like is the alternator whines. Been two months still whining.

    Great Product!

    Check engine light came on (code 0340 -camshaft position sensor). Replaced both sensors to no avail. Did a quick search and found several forum posts suggesting that alternator would be the actual cause. My OEM alternator had 149k miles on it. Ordered this alternator because it was actually cheaper than the 135 amp model and you get 15 more amps output. Swapped it out in less than an hour. No more check engine light and codes gone immediately. Runs smooth and no issues so far. SR so far has not disappointed with their products. I also purchased their water pump last month. Made in America products at a great price! Keep up the awesome job guys and a huge shout out American Muscle for carrying their products!

    SR Performance Alternator - 150 Amp

    I'm not a mechanic but thanks to AM and Youtube, I replaced the alternator by myself. There is a video on youtube that show how to change it and once you know how, it's pretty simple. I upgraded the Amp from 130 to 150 because my after market radio blew the original alternator. After this incident, I read on the many Mustang Forums that it's a very commun complain. The Mustang is so heavily computerized that everything is meant to work together as it is when it leaves the Ford dealership. The new alt does make a little noise when the hood is open, but it's not loud enough to be heard when it's closed.

    Fried

    Unfortunately the alternator fried the power cord and i had to put back my oem alternator. To be sure there is no more damage, i am sending the car to dealership to get an electric diagnostic.
