ACDelco Gold (Professional) Remanufactured Alternators are the high quality alternative to Original Equipment (OE) parts. These alternators use high-quality bearings with high-temp lubricant 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 with new components. Damaged and obsolete parts are replaced and are end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. ACDelco Gold (Professional) parts are manufactured to meet your expectations for fit, form, and function, making them a smart choice for General Motors vehicles, as well as most makes and models, including special applications. These high-quality parts are backed by General Motors. Some ACDelco Gold parts may have formerly appeared as ACDelco Professional. ⚠ WARNING: Cancer and Reproductive Harm - https://www.P65Warnings.ca.gov

Features and Benefits:

  • Alternators use high-quality bearings with high-temp lubricant and double-lipped rubber seals, reducing friction, vibration, and noise
  • Performance-tested and inspected to ensure they meet your expectations for quality design and component specifications
  • Remanufactured using consistent quality processes; not just rebuilt
  • Remanufacturing is an industry standard practice that returns parts into service rather than scrapping them
  • Rotors and stators are electronically tested and then sealed with secondary insulating coating to help prevent shorts
  • Tested to ensure they perform to ACDelco specifications
