      • 100% New Replacement
      • Includes Manufacturer One Year Warranty

      100% New. This 170 Amp Mustang Alternator is 100% Brand New, not re-manufactured like other companies sell and is tested at the time of assembly. It comes complete with internal voltage regulator and pulley. The 170 Amp alternator will increase the charging capacity at all RPM Ranges with no modifications required.

      More Power. The PA Performance Alternator produces 90+ amps at idle (2000 alternator shaft RPM), and 170+ amps at maximum (6000 alternator shaft RPM). It is required to upgrade the main power wire because this alternator has a higher output than stock. (See the drop down menu option above).

      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 altenator that includes a Limited One Year Warranty directly from PA Performance for peace of mind.

      Application. The PA Performance Alternator weighs in at 14.2 lbs and is a direct 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.

        Its freaking awesome!!

        I've had it for about 3 months now and so far do good. I had an electrical issue with my ac, I went through 3 different alternators from advance auto parts until I said f this... so I spent the money and bought this one. I like it. Not to bad. Price could've been cheaper... though

        So far it has been great! I installed it together with the aftermarket wiring from PA performance. No more battery light flashing at full throttle and so far no more battery issues. I used to go through batteries and alternators often. I don’t suspect this will happen any more.

        Absolutely amazing.

        This alternator is amazing. When I turn on everything like the A/C, headlights, step on the brake, all at the same time, the battery gauge doesn't flinch. Its been about two months I think and its still going strong.

        Very efficient and reliable with a decent price

        It was a replacement to a failed stock alternator. Very reliable, easy to fit as a replacement for the stock one. Higher amp's than stock. Don't go cheap on your car and get the premium power wire with it since the stock wire tends to fail when installing a higher output alternator.

        I needed a hp alternator due to installing an amp and nee stereo system in my 04 GT. This solved my battery light problem. I bought the hp cable too. Glad I did!

        Great product and fast shipping

        I was really surprised with how fast it got to my house. It was really quick. The alternator was packaged perfectly and it came in great condition. I just installed it with the power cord and everything works great. My intermittent battery light went away. I will be bring from American Muscle again.

        Great product with lifetime warranty

        Before this alternator i had battery light problems which slowly became worst until one day it came on at every rpm. This alternator corrected it & if i want to put a underdrive pulley on it i have the option. Bottom line AM had it when i needed it & shiped the item quick, i've had p.a performance parts before thAts why i trusted this.

      I broke 2 of the bolts that go from the bracket to the alternator, can you supply new bolts if I buy this unit?

      Can you run an electric water pump and under drive pulleys with this alternator or a 130 amp?

      • The use of underdrive pulleys will void the warranty on a PA Performance High Output Alternator. This Alternator will provide enough power to run your electric water pump.

      How will installing a high-output alternator affect the performance of other related parts? Mach 1000 audio system, underdrive pulleys, etc?

      • With the PA Performance High Output Alternator - 170 Amp you may notice those electronic components performing better. For example your audio system may come through a little cleaner and your headlights and interior lights may brighten a bit. This will not have any affect on your under drive pulleys.

      • Yes, the PA Performance High Output Alternator - 170 Amp (99-04 GT) would work for your Roush, however the Cobra alternator would not work.
