Review & Install Video

100% New. This SR Performance 130 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 130 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 130 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.

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.

Clutch ? Does this altenator have the clutch like the factory altenator ?

  • In respect of your question, I have just fitted the alternator straight from the box into my 2006 Mustang GT based in the UK. It took me 35 minutes, and so far having done 40 miles in traffic and fast roads 80mph, I can report it seems to work fine. No additional parts required!

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.

  • Using your original clutch pulley with the SR Performance Alternator - 130 Amp (05-08 GT) should not be a problem.

    The alternator is top notch, you can tell from the moment you take it out of the box. Very high quality and it is so easy to install that it will take you longer to gather the necessary tools. It is more expensive than the stock one but well worth it. It is a must/good upgrade for your Mustang.

    good choice

    2006 GT, CEL at 63k, P0340 cam shaft sensor. alt started to fail (1 bad diode). looked at a few different alts. SR was a good choice, worth the $. 1.5 hrs easy fit, remove air intake and throttle body (clean when off). perfect fit. no alt whining. solid charge. no more CEL.

    It fits

    It is an alternator. It is new. It is a relatively easy install (less than 2 hours -- that includes removing and cleaning the throttle body and tool setup and cleanup). I went ahead and removed the throttle body in order to give myself more access. I used a bungee cord to hold the serpentine belt in place. There are a number of online videos showing how to install the unit. We will see how long it lasts. No improvement in 1/4 times; however, the P0330/P0334 codes went away. More importantly, the battery voltage with the car running reads a steady 14.6 with all accessories running. Prior to the installation, my voltage with all accessories was under 12. Factory alternator died after 69K miles and 50 or so 1/4 mile passes.

    So far so good

    My 05 was kept throwing codes for the camshaft position sensor and crankshaft position sensor. Car would jolt/surge, CEL was constantly on even after replacing sensors. Alternator and battery tested fine but decided to go ahead and replace the alternator anyways. CEL went off, codes went away, car is runny great again. Pretty tight fit if you have aftermarket pulleys but it will still go on with some maneuvering.

    Nice Replacement!

    My stock alternator failed after 82,000 miles on my 06 Stang. I was throwing cam sensor codes and this is definitely the fix as posted on Mustang Forums. So far so good no more codes and car is running smoothly. A little pricey, but worth it!

    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!

    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!

    Like many others, I got the code p0340 and looked up what it could mean. Bought this alternator and it definitely did the trick. No more CEL.

    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.

    Worked for 1 week!

    I got this alternator as a stock replacement after 165,000 miles. This SR Performance alternator failed after one week! Voltage regulator was shot, radio and lights would constantly flip on and off. Ordered a new one and haven't had a problem yet, one week later. knock on wood!

    Good replacement for stock

    I had my OEM alternator all the way up through 165k miles. Was getting two codes(cam and crank sensors) which is resulted in check engine light. This replacement got rid of the issues and minor stuttering I was experiencing. The only problem I had was right after install where the belt was smoking from trying to turn the alternator over. I am not sure if it was damaged in the mail or just needed broken in? Either way, the smoking was gone after a 10 minute drive and I haven't had a problem since.

    So far it working great!

    I got this new replacement due to my check battery light being on for many months without having an actual battery issue. We came to the conclusion that the problem might be the voltage regulator in the old alternator. So far after replacing it, the issues have gone away. Very happy with the product. Always fast delivery of their products as well.
