ACDelco 18A2804B Gold Fully Coated Front Disc Brake Rotor

The ACDelco 18A2804B is a Gold series fully coated front disc brake rotor engineered to deliver reliable, quiet stopping performance. As part of ACDelco's Gold line, this rotor is manufactured to meet General Motors' expectations for fit, form, and function, making it a high-quality alternative to OE parts for GM and compatible vehicles.

Key Features:

• Full corrosion protection coating — robotic-applied, baked-on finish helps prevent rust, brake pulsation, and rotor-to-hub seizing from harsh environmental exposure including rain, snow, and road salts
• Mill-balanced construction — inspected for balance to deliver smooth brake operation and reduced noise and vibration
• Non-directional ground finish — minimizes thickness variation and helps extend brake pad life
• OE vane configuration — application-specific venting maximizes airflow, dissipates heat, and dampens noise during braking
• G3000-qualified cast iron material — meets SAE structural integrity standards with multiple alloys for improved heat dissipation and performance
• Tight thickness tolerances — thickness variation of less than 0.0004 inches minimizes pedal pulsation and noise
• No machining required — ready to install straight out of the box
• Independently tested — validated through Noise/Vibration/Harshness (NVH) and durability/wear testing

The ACDelco 18A2804B is a front, vented disc brake rotor. It is sold individually. ACDelco Gold brake rotors are backed by GM and supported by ACDelco's limited warranty program for added peace of mind.
