ACDelco 18A724AC Silver Coated Front Disc Brake Rotor

The ACDelco 18A724AC is an ACDelco Silver (formerly Advantage) coated front disc brake rotor engineered to deliver reliable stopping power backed by General Motors. The "AC" suffix designates the factory-applied corrosion-resistant coating, making this rotor a direct-fit, ready-to-install replacement for a wide range of GM and non-GM vehicles.

Key Features:

• Robotic-applied, baked-on coating provides superior rust prevention against rain, snow, and corrosive road sprays, and helps prevent the rotor from seizing to the hub
• Non-directional ground finish minimizes thickness variation and helps extend brake pad life
• Application-specific vane configuration optimizes airflow for improved heat dissipation, reducing brake fade and improving performance
• Mill-balanced construction for smooth, quiet brake operation and noise/vibration/harshness (NVH) reduction — no extra weights required
• Multi-alloy cast iron construction validated for proper metallurgy and correct brake plate thickness
• No machining required — installs straight out of the box
• Independently tested for durability, wear, and NVH performance
• Backed by General Motors

ACDelco Silver brake rotors are a high-quality, high-value alternative for GM vehicles as well as most other makes and models. For best results, pair with ACDelco Silver or Gold brake pads to ensure a properly matched braking system.
