ACDelco 18A82457B Gold Fully Coated Rear Disc Brake Rotor

The ACDelco 18A82457B Gold Fully Coated Rear Disc Brake Rotor is a high-quality replacement rotor engineered to meet OE specifications for fit, form, and function. Part of the ACDelco Gold (formerly Professional) line, this rear rotor delivers the precise engineering and dependable stopping performance expected from a GM-backed brake component.

Key Features:

• Full corrosion-resistant coating — robotic-applied, baked-on finish helps prevent rust, reduces rotor-to-hub seizing, and guards against harsh environmental elements including rain, snow, and road spray
• Mill-balanced construction — reduces vibration and noise for smooth, quiet braking operation
• Non-directional ground finish — helps extend brake pad life and minimizes thickness variation
• Full cast, conventional design — cast iron construction for long-lasting durability and consistent heat dissipation
• Ready to install — no machining required right out of the box
• GM-backed quality — manufactured to meet General Motors expectations and backed by a 24-month/unlimited-mile limited warranty (parts)

The ACDelco Gold line goes through the same rigorous quality approval process as OE parts, making the 18A82457B a reliable choice for drivers seeking OE-level performance at a competitive price point. Cross-reference part numbers: 18A82457, 18A82457A, 18A82457B.
