ACDelco 18A81017AC Gold Fully Coated Disc Brake Rotor

The ACDelco 18A81017AC is an ACDelco Gold (Professional) fully coated disc brake rotor engineered as a high-quality alternative to Original Equipment (OE) brake rotors. Mounted to the wheel hub, this disc brake rotor works in conjunction with the brake calipers and pads to deliver reliable, confident stopping power.

• Mill-Balanced Construction: Precision mill-balancing ensures smooth operation and reduced noise — no additional weights required
• Non-Directional Ground Finish: Helps minimize thickness variation and extend brake pad service life
• Ready to Install: No machining required straight out of the box
• OE-Quality Metallurgy: Manufactured with G3000-qualified material to meet SAE structural integrity standards and OE specifications for fit, form, and function
• Backed by General Motors: ACDelco Gold parts are engineered to meet GM's exacting standards and are suitable for GM vehicles as well as most other makes and models
