ACDelco 18A82000C Gold Fully Coated Front Disc Brake Rotor

The ACDelco 18A82000C is a Gold-line fully coated front disc brake rotor engineered as a high-quality alternative to Original Equipment (OE) parts. Backed by General Motors, this vented rotor is manufactured to meet stringent standards for fit, form, and function across GM vehicles and a wide range of additional makes and models.

The protective coating provides superior corrosion resistance compared to non-coated rotors, validated through up to 200 hours of industry-standard salt-spray testing. This helps inhibit rust formation on non-friction surfaces, prevents the rotor from seizing to the hub, and contributes to a cleaner, longer-lasting installation.

Key Features:

• Fully Coated Design: Micron-thin protective coating resists environmental corrosion on non-friction surfaces
• Tight Thickness Tolerance: Thickness variation of less than 0.0004" minimizes pedal pulsation, noise, and brake pad wear
• OE-Matched Material: Cast from G3000-qualified iron meeting SAE structural integrity standards
• Vented Construction: Internal vane design dissipates heat generated during braking for consistent stopping performance
• No Machining Required: Ready to install straight out of the box
• GM-Validated Quality: Engineered, designed, and tested to meet General Motors performance expectations
• Sold Individually: One rotor per package

ACDelco Gold disc brake rotors undergo Noise/Vibration/Harshness (NVH) and durability/wear testing to deliver quiet, reliable deceleration and smooth, predictable stopping power. The ACDelco 18A82000C is the coated upgrade to the base 18A82000 rotor and may also be referenced alongside GM part number 19387950.
