ACDelco 18A2841B Gold Front Disc Brake Rotor Vented Coated

The ACDelco 18A2841B Gold Front Disc Brake Rotor is a high-quality replacement disc brake rotor engineered to restore reliable, smooth stopping power. Part of the ACDelco Gold (Professional) line, this rotor is a GM-recommended alternative to Original Equipment parts, designed to deliver the fit, form, and function expected from a General Motors-backed component.

This vented front rotor features a cast iron construction with a 5-lug bolt pattern and a protective coating that guards against rust and corrosion, helping prevent rotor seizure to the hub and extending service life. The non-directional ground finish minimizes rotor thickness variation for consistent pad contact and reduced brake pedal pulsation.
