I originally bought this a few years ago, but dont need it anymore. I just got it back from Nathan after the front pulley came loose, had it fixed and looked over (rebuilt) and sent back. Somewhere in shipping a piece of the case got cracked, but I still have the pieces if you want to glue it back. I honestly didnt notice it until a few days. This is a 250amp alt for 99-07 gm trucks/suvs, im not sure what else it will fit. I paid $430 for this 2 years ago.
If you google excessive amperage youll see nathan is a highly respected alt dealer and makes a good product.
Pulley sold, price on the alt dropped to $250 shipped OBO

sounds good to me.
i'm looking to get some good speakers and a four-channel amp. between the speakers and my sub, i'll probably have 600 to 1000 watts. you think this will handle it?

definitely, this alt is a beast. I have 1500w of stereo, 500w of lights, and compressors that draw over 50 amps together (700wish), and just to test it out i turned on everything just idling and saw maybe .2v drop, rev it up to 800rpm and alt was putting out 14.1v with everything on.







why do you ask?
