Great alternator I put this on a 5.3 LS in my 2004 avalanche and I can say you definitely need a slightly longer belt for sure

Have an old Silverado. No performance crap, no subs, no extra heavy loads. Aftermarket alternators last me 2 years under normal circumstances in this truck.Tried this one because I know speedway, and it’s black so it looked nice. Voltage drops at idle to 12.4 volts. Surging back up when you touch the pedal. It makes the whole truck act strange.Can anyone make an alternator like the OEM that came on the truck. Guess not.
