Your cart is empty. ACDelco’s Professional Remanufactured Alternators are the ideal high quality replacement for many vehicles on the road today. ACDelco’s Professional Remanufactured Alternators use high-quality bearings with high-temp lube and double-lipped rubber seals. Rotors and stators are electronically tested and then sealed with secondary insulating coating. Remanufacturing alternators is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear and failure with new components. Damaged and obsolete parts are replaced and are 100% end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing also benefits the environment by returning components back into service rather than processing as scrap or simply disposing of them. These premium aftermarket reman alternators are manufactured to fit a wide range of vehicles and will provide the same performance, durability, and service life you expect from ACDelco.
ACDelco Professional Starters and Alternators get your vehicle started and keep it running. ACDelco’s Professional line features both NEW and remanufactured starters and alternators for both GM and non-GM vehicles. They are 100% performance tested and feature competitive warranties to give you the confidence you need.

I read the reviews and gambled because I needed it quickly. Alternator worked fine until the pulled decided to become two pieces after about a 100 miles. Amazon was easy to work with on return but was disappointed that it failed the way it did.

It was a alternator fir a tractor. 30 min to swap old to new. 10 min use and drive pulley split and failed. It was milled to thin. Put pully from old alt to new to repair. It would have been Waste of time to send back. I need it fixed. Alt then worked but after a my two hr repair time. Alt was cheaper from Amazon but I got what I paid for, cheaply made part. Buy local, pay more but get better quality and easier company contact. Amazon didn't make the cheap part? But they did sell it.

Searched alternators for an old (81) motorhome, and this one came up as the right fit for it. As it turned out, the old one had been mickey-moused into the engine compartment, and my mechanic said it was lucky it didn't start a fire!!! He finally located the right plug, then had no trouble installing this Delco alternator into my vehicle. It is running as it should, charging the battery.
