ACDelco 18A82457C Gold Coated Rear Disc Brake Rotor

The ACDelco Gold 18A82457C is a fully coated rear disc brake rotor engineered as a high-quality alternative to Original Equipment (OE) parts. Part of the ACDelco Gold (formerly Professional) line, this rotor is manufactured to meet General Motors' standards for fit, form, and function, making it a reliable choice for GM vehicles as well as a wide range of other makes and models.

This rotor is constructed from G3000-qualified cast iron and features a full protective coating applied to help prevent rust, inhibit rotor seizure to the hub, and resist corrosion from harsh environmental elements including rain, snow, and road salt. The coating is applied robotically and baked on for long-lasting protection.

Key Features:

• Full cast iron construction — G3000 qualified material meets SAE standards for structural integrity
• Full protective coating — corrosion-resistant finish provides superior rust prevention right out of the box
• Rear disc brake rotor — conventional, solid (full cast) design
• Thickness variation less than 0.0004" — minimizes pedal pulsation, brake noise, and extends brake pad life
• Mill-balanced — engineered for smooth operation and noise reduction
• No machining required — ready to install straight out of the box
• Backed by General Motors — 24-Month/Unlimited-Mile Limited Warranty (parts only; parts and labor if installed by a GM dealer)

ACDelco Gold parts go through the same rigorous 18-step quality approval process as OE components, ensuring consistent performance and durability. The 18A82457C is sold individually and is designed for use on select Cadillac, Chevrolet, and GMC vehicles.
