Product Information

Description:

GENERATOR ASM, (SLP)

GM Genuine Parts Remanufactured Alternators are designed, engineered, and tested to rigorous standards, and are backed by General Motors. 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 GM specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). ⚠ WARNING: Cancer and Reproductive Harm - https://www.P65Warnings.ca.gov

Features and Benefits:

  • Remanufacturing is an industry standard practice that returns parts into service rather than scrapping them
  • Some ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco Professional
