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.

  • 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.

does this give you any hp and torque boost??

  • I did notice the pulley on this alternator had a smaller diameter of the oem alternator on my car. So, if there is a boost, possibly less drag on the engine. But I doubt there would be a go boost if at all noticeable

    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

    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!!!!!!

    I can feel the power

    Not saying I feel more hp , just saying I can feel the car hold its power. I like the price, I had to go to a local shop to install only cuz I have sr pulleys and the main pulley blocks a blot also the pulley on the new alternator had to be switched out with the sr pulley. I almost did it myself just those last to things, so yeah shop did it.
