1999 GMC Sierra 4x4, does  alternator come with pulley? Also you have 105 amp and 145 amp, what is the difference?William B.Nov 01, 2023
Best Answer:Hi William, thank you for reaching out! Yes, it comes with a pulley. The 105 and 145 amps are not interchangeable. You need to check what you ave prior to buying. Have a good one!

Customer Reviews

Professional Series Alternator, New
A hiccup but handled very well. Definitely a good vendor!
While the first delivery showed the alternator damaged, <a href="http://CarParts.com" target="_blank">CarParts.com</a> quickly (like hours, not days later) had a new alternator on its way to me. It arrived the next day and everything went together correctly from that point on. The damage showed on the inner box so it had been poorly handled at the CP warehouse, not by the shipper. Still, CP handled the issue promptly and had the return shipping label to me right away so the shipper could pick that return up
