i think it's actually a 250 amp alt, but i would rather undersell it than over sell it. i paid $220 shipped for it. it has been in my car for about 6 months w/o any problems, was only charging starter battery-- i dont even have a head unit at the moment. I am looking for $180 shipped, however, I am open to offers. The alt is from an 04' GMC Denali 6L and should fit 00-06 I believe.
