i got the stocker...i dont see why it would only last a year. summit racing has some, but their 400 something dollars. my stock one lasted 5 years, put a stock replacement and its all good
I had the same problem with mine. Best sloution is to get a capacitor from an electronics store and hook it up to your system. Theyr'e kind of expensive but it's better than replacing the alternator every once in a while.
i would get a higher rated alternator. we have the same problem with plow trucks.. they blow up alternators when plowing. ford offers high amp alternators for the crown vic with the 4.6 for the police cars. i am not sure if the plugs match up but i would look into that and see what the amp rating is for that unit compared too the stocker.
