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.

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.
