ACDelco 18A937B Silver Coated Front Disc Brake Rotor

The ACDelco 18A937B is a Silver series coated front disc brake rotor engineered as a high-quality, high-value alternative for General Motors vehicles as well as a wide range of other makes and models. Backed by General Motors, this rotor is designed to restore smooth, quiet, and predictable stopping power.

Key Features:

• Corrosion-Resistant Coating: Baked-on finish helps prevent rust and corrosion, inhibits rotor seizure to the hub, and reduces brake pulsation
• Non-Directional Ground Finish: Minimizes thickness variation and extends brake pad life for consistent braking performance
• Multi-Alloy Cast Iron Construction: Engineered with multiple alloys for improved heat dissipation and resistance to brake fade under repeated stops
• Mill-Balanced Design: Ensures proper rotor function with no additional balancing weights required
• Validated Metallurgy: Quality-checked for proper metallurgy and correct brake plate thickness to support reliable braking under real-world thermal stress
• Rounded Radius Edges: Increases structural strength under high heat and load conditions
• OEM-Backed Engineering: Designed, engineered, tested, and backed by General Motors

The ACDelco 18A937B is sold as a single rotor. For best braking results, rotors should be replaced in axle pairs and paired with fresh ACDelco brake pads.
