ACDelco Gold (Professional) Fully Coated Disc Brake Rotors are the high quality alternative to Original Equipment (OE) parts.

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

  • Manufactured to meet specifications for fit, form, and function for General Motors vehicles as well as most makes and models
  • Premium aftermarket replacement part
