ACDelco 18A81048C Gold Vented Front Disc Brake Rotor with COOL SHIELD Coating

The ACDelco 18A81048C is a Gold series vented front disc brake rotor engineered as a high-quality replacement for General Motors vehicles. Featuring ACDelco's COOL SHIELD™ coating, this rotor receives a baked-on zinc treatment across the entire surface—including edges and vanes—providing superior corrosion resistance proven in up to 200 hours of industry-standard salt-spray testing.

Key Features:

• COOL SHIELD™ Zinc Coating – Full-surface baked-on zinc coating resists rust and corrosion, keeping the rotor cleaner longer than non-coated alternatives
• OE-Matched G3000 Material – Meets SAE standards for structural integrity with OE-qualified cast iron for guaranteed performance
• Tight Thickness Tolerance – Thickness variation of less than 0.0004" minimizes pedal pulsation, brake noise, and premature pad wear
• Vented Design – Internal venting dissipates heat generated during braking to prolong rotor and pad life
• No Machining Required – Ready to install straight out of the box
• NVH Tested – Independently tested for Noise, Vibration, and Harshness as well as durability and wear performance
• Sold Individually – One rotor per package

ACDelco Gold disc brake rotors are GM-recommended replacements manufactured to meet specifications for fit, form, and function. By maintaining consistent friction surfaces and supporting the full hydraulic braking system, this rotor delivers smooth, predictable stopping power and reliable deceleration for everyday driving.
