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 1999-2004 GT Mustang. The stock belt can be used on original equipment vehicles.

Great replacement alternator!

Installed with no issues and works better than original. Swapping to an underdrove pulley was a cinch as well.

Will this fit 2003 Saleen Mustang 281sc convt?

xvicx

  • For the SR Performance Alternator - 130 Amp (99-04 GT), we cannot guarantee fitment for this on a 2003 Saleen Mustang 281sc convertible. If you give Saleen a call, they could give you an answer since the 281sc is a factory supercharged car.

  • The SR Performance Alternator - 130 Amp (99-04 GT) does not have a warranty attached to it, but American Muscle does offer a 30 day return policy on almost all items, this included.

    Great Place for parts

    I love American Muscle, is very easy to find stuff and most likely they have it in stock so orders arrive fast. This alternator is perfect, it does the job and its affordable however the people in charge of answering questions and giving deadlines could be a little more serious, meet the deadlines and if the answering team dont know the answer to a question make sure to put a little effort in finding out for sure before recomending to go ahead in a big purchased this is not my first buy from this store and i use to recommend to everybody. Great store, but never taking advice again and a little disappointed

    SR PerformanceAlternator 150 Amp

    My 2000 Ford Mustang GT was flashing the battery light with a dimming effect on the interior lighting and the headlights, and I notice it was random and usually happens during acceleration. I decided to replace the alternator, as the voltage regulator was likely going out. This is the second time I've replaced the alternator through American Muscle. The alternator, a SR Performance Alternator - 150 Amp, arrived on time in 3 business days. I was able to swap the old alternator out with the new one in a little under an hour, 54 minutes to be exact. I had a friend to help with the belt tensioner, to hold it in place while I maneuvered the belt to a safe spot to remove the alternator. It was a perfect, OEM fit. It removed the symptoms the old alternator was producing, and restored constant brightness to my headlights and interior lighting. All of the bolts, nuts and washers needed for installation are either pre-existing hardware found on your current alternator, or provided with the product. It came with a warranty, that only requires you to keep the box. I strongly recommend this product if you either: --Have a battery light problem / dimming headlights --Have a malfunctioning alternator requiring a direct replacement. --Are upgrading your stereo / speaker configuration and need more power from your alternator.

    Works Great!!!

    My old alternator that came stock on my 2002 Mustang GT has 164,000 miles on it and be an making a buzzing/humming sound both under the hood and in my rear window speakers. I replaces it with this 135 Amp alternator and it fit PERFECT! It's now VERY quiet and no more buzzing/humming!!! I highly, highly recommend this Alternator!!!!!!

    very nice piece

    My original alternator was starting to fade so I started to look around for a new one. This was about 1/2 the price of most new alternators and less expensive even than rebuilt ones. The install was a snap; less than a 1/2 hour and its indistinguishable from stock. Time will tell how it holds up but so far its perfect. Why pay more?

    Great Alternator, Fits perfectly.

    I was skeptical about the price at first but I have bought SR Performance parts before and like the other times, I am not disappointed. I had bought 2 other alternators in one year so I am glad this alternator has had no problems. Great product for the price.

    Looks great

    I bought this went my stock alternator went out. First had a slight miss at low throttle under acceleration when cold. Then the battery warning light would come on and go off. Battery light came on and the gauge on the battery went down until the car shut off. Had to town the car and ordered this. Can't wait to install it. The box says 150amp so not sure if it's 130 or 150 amps

    Great product for an awesome price

    Alternator shipped super fast and was well packed from the supplier. AM site states 130 amp but the box from SR Performance states it's 150 amp. Quick and easy install. Alternator has been performing flawlessly for about 2 weeks. My OEM alternator was only putting out about 12V, with the SR Performance alternator I am producing 14.4V. Would not hesitate to purchase this item again and recommend it to anyone that does not want to pay the OEM or autopart store replacement prices.

    Love it!

    So i bought this alternator because my stock alternator started to whine when i would turn on the headlights. First off, the price is unbeatable. I went to oriellys and they quoted me at 210 for a refirbished one..no way i was going to pay that. So i began looking here and came upon the sr performance alternator. Bought it and got to me in about 3 days whoch is awesome! When i recieved it all i had to do was go back and follow the step by step guide and only took me 30 mintues to unistall the old one and install the new one! Car fired right up and runs great!!!! Thanks AM you guys are doing awesome!

    Bought this alternator cause it looks nice, and is an upgrade from the factor 130 amp alternator. Anyone can install it! Super easy!! Took me a half hour tops, and I have just basic knowledge. No noises or anything like that. You don't have to remove your water pump pulley! Just looses the bolts with a wrench! You'll understand
