Item was a perfect fit! Sad part it was broke when received so had to modify it for use. Overall great replacement and piece was okay. not as functional as we needed. Overall great color match, semi functional, fit perfect.

I've been running this alternator for 4 years on my 02 silverado. The pulley was a little bigger than stock but it fit. I have no way of measuring the output but it has done a good job powering various accessories.

Beware to check your harnesses. This alternator almost fits. Went to install it today and everything looks good except the wiring harness plug.Can not return due to waiting to long to install.Guess i learned an expensive lesson

I added a ridiculously large winch to my 2000 S10 Blazer. The winch draws obscene amps when under even the most moderate of loads which the factory alternator and battery were never intended to support. This alternator coupled with a 1100 CCA battery power not only my winch when needed but all the other electrical add ons I’ve crammed in it. If upgrading from a stock alternator as I did, be sure to also upgrade the charging cables to your battery and alternator as well as the grounds. I did what is commonly referred to as a “Big 3” upgrade with custom made super thick 00 welding cable.None of what I did was too extremely difficult if you’ve got some basic mechanical skills, creativity and persistence.I’ve only had it installed for about 2 months now so I can’t really speak to how long it will last. What I can say is I’ve put it through some very strenuous workouts pulling everything from large logs to a F350 Super duty stuck to its axles in thick wet mud and it’s done it’s job superbly. I have to think that if it were going to fail or be short lived, I’ve done all I could to cause it to.I’m very please with the performance and value from this alternator. There are others on the market probably built a little more robustly but they also cost about a third to one half more.I would recommend it!

Absolutely the BEST CUSTOMER SERVICE I've EVER received.Super fast shipping.AJ-Electric is one of the best businesses on Amazon!!The Alternator is for my 2004 GMC Envoy XL Slt 5.3 V8.Envoys seem to have power problems later in life plus I have Kensun HID headlights and fog lights which were draining my battery so my headlights weren't bright.After installing my new 250amp Alternator my battery voltage went from 11 to 15 even with my headlights on.Now my Envoy has more power and my headlights are BRILLIANT and I can see almost a full mile.This is a must buy for any Large Truckor SUV.Best choice I've made and the price was much lower than others on Amazon or Ebay.Don't miss out.Thank you Mr.Ferrari!Will definitely purchase from this company in the future if needed.

Alternator is definitely brand new. Apprehension set in though as the higher output alternator was a little larger than the high amp OEM GM alternator (98 Silverado). The new alternator bolted right in. I had to bump the idle of the truck up just a bit, probably less than 100 more rpm. At 600 RPM the new alternator was pushing 14volts out (per the cluster gauge). This kept the retrofitted 2 electric fans running at the required speed, radio amp, headlights etc perfectly bright. The older alternator could't push the volts out at idle. Hoping over time this new alternator holds up, but the workmanship and design appears to be spot on. Recommended and would purchase from them again. The price was right too.
