Description

ACDelco Gold (Professional) Fully Coated Disc Brake Rotors are the high quality alternative to Original Equipment (OE) parts. These rotors are mounted to the wheel hub where the calipers can press the brake pads against the brake surface to help slow the vehicle. 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
