Best Automotive Performance Alternators & Generators

ACDelco 334-1115 Professional Alternator, Remanufactured
Remanufacturing alternators is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear with new components. Rotors and stators are electronically tested and then sealed with secondary insulating coating to help prevent shorts.

Reviews
"I wouldn't say this is 5 stars because of that bending, I assume the metal is cheap and hopefully not hollow, but for what it's worth, I'm not running 1000 hp, this works for a daily driver."
"works but is not really made for a small block , will need to take out a intake manifold bolt and use tube spaces to make fit all is included , just won't be what you expected."
"I could not use the top part of bracket did not fit my set up but the rest of it fit fine."
"Building my own backup generator, this is a must have to mount the alternator."
"although it fits somewhat it is smaller than I thought and to use it I would have to replace the fan belt and then the alternator would sit to high."
"again what's not to like."
"Description said was for a long water-pump and it is not even close, but of course package is open and I have extra alternator brackets lying around.Nicely made just wrong totally."
