Dynamic Friction 4822-31144 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4822-31144 is a GeoSpec Coated plain (smooth/blank) disc brake rotor engineered as a direct OEM replacement. Featuring DFC's proprietary GeoSpec® corrosion-resistant coating, this rotor delivers a durable, attractive silver-gray finish that provides superior rust protection compared to conventional zinc plating or standard paint coatings.

GeoSpec® Coating Advantage:

• Processed dry and shipped dry — ready to install with no additional pre-degreasing or preparation required, saving time and labor during the brake job
• Superior corrosion resistance over conventional zinc plating and standard paint coatings
• Attractive silver-gray hat finish that maintains appearance over the life of the rotor
• Coating is safely swept away by friction material during normal break-in with no harmful effects

Key Features:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• OE vane configuration ensures proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for precise fitment
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter, smoother stops
