Review & Installation 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.

Will this amp be able to supply enough power to keep up with the Mach 1000 sound system in my 2003 gt?

The SR Performance Alternator will output a maximum of 130 amps, 20 amps more than the OEM Alternator's 110 amp maximum output. This will be more than enough to keep up with the Mach1000 stereo.

Helpful (2)

My alternator was blowing fuse cause it was outputting too much power will this one do the same it’s for a 2000 mustang gt

The SR Performance Alternator will peak at 130a output. This should not blow the stock fuse.

does this give you any hp and torque boost?? 2 answers

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
no, it did not.

Was Bad on Delivery

The alternator fit great but, when under a load, it whined like crazy. I called AM and, due to there not being any being in stock for the next 2-3 weeks, they are refunding my money and they sent me an RMA UPS label. I wish i could rate the service and the product differently. I would give AM 5 stars for service but this alternator 1 for being essentially DOA.

Epic results

had a problem with the red battery light on the dash, everything tested out ok, alt showed good battery was good, i tried everything and still had a light. i finally broke down and bought this alt. and picked up the SR powerwire kit to go with it., took about 40 minutes in the driveway and i have no more red light :) easy job with great results. American Muscle was wonderful to work with and will be my one stop mustang shop.
