      • 3G Series Alternator
      • 100% New! - Never Rebuilt
      • Direct Fit Replacement
      • 130 Advertised Amperage
      • 12 Volt Compatibility
      • Fits 87-93 5.0L, 94-95 GT & 94-00 V6 Mustangs


      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 70 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.

      Required Upgrade. It is required to upgrade the main power wire because this SR Performance alternator has a higher output than stock. (See the drop down menu option above.)

      Application. The SR Performance 3G Series Alternator is nearly a direct replacement with only minor mounting bracket modifications required to be installed in a 1987-1993 5.0L, 1994-1995 GT and 1994-2000 V6 Mustang. The stock belt can be used on original equipment vehicles.

        Beware of lack of information

        This product arrived, is not a direct bolt in, came with no instructions for dealing with the wiring changes or the modifications required for mounting. I found a competitors video to help me sort all those issues out...however I could not find a kit to deal with the plug again I found the stator wire plug I needed elsewhere. This really should have included a wiring kit and conversion instruction since it says it fits my application. Won't accept my under drive pulley...the shaft is too short and it would not leave enough threads. The product is probably fine...I'm still waiting for parts to complete the install. I just did not like the surprise or the trouble I had finding what I needed to know.

        Solved my problem

        Between my ud pulleys and electric fan I was having electrical issues, battery constantly dying, low charge. This put me where I needed to be. Simple bolt on. 15 minutes tops to do. Super pleased

        Good product for the money, would recommend. Not having problems with the stereo system dimming my headlights at night. Needed minor modifications to the existing bracket but the over all installation was not a big deal.

        4 1989 GT - CAndr Installation Time: Afternoon

        Worked Like it should

        The product came fairly quickly in the mail. There box was a little short on "filling" which allowed the alternator to move around quite a bit in the box. The guide provided for this alternator was not correct for my year model, so I had to go to a different alternator and view that guide to see how to install it. Something needs to be said about the customer needing a different spade plug-in. Stock is 3 spade and SR is 1. After we got the alternator installed, which was easy once we had the correct guide, the car has a stronger voltage reading. The alternator did its job. I loaded the car up with lights, radio, AC , side windows, at idle and the alternator held the battery at an acceptable voltage. It wouldn't have been able to before.

      I’ve had this for a couple years now, it’s making bad bearing noises, is there a part number on this?

      • SR Performance does not offer parts of this alternator separately, so there would not be an item number to lend.

      Hello, I just bought this and I was wondering if there is any need to modify placement(bolts) on a 98 v6? Or is it going to directly bolt on where the old one was? Thank you

      • This SR Performance Alternator will re-use the original existing hardware that held your factory alternator in the vehicle. There is no need to upgrade/replace unless the condition of the hardware is poor.

      Will this alternator fit on a V8 5.0 1985 Fox body mustang? I am asking because all the alternators say their for 87 and up.
