Dynamic Friction 4822-63129 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4822-63129 GeoSpec Coated Brake Rotor is a premium plain (blank) disc brake rotor engineered to deliver reliable, quiet, and vibration-free stopping power for cars, SUVs, and trucks. Featuring DFC's patented GeoSpec corrosion-resistant coating, this rotor arrives fully protected inside and out with a durable silver-gray finish that resists rust far better than conventional paint or zinc coatings.

Key Features:

• Full GeoSpec Coating: Completely coated inside and out with a patented rust-prevention finish — no cleaning required before installation
• Premium G3000/G11H18 Iron Casting: Engineered for superior strength, stability, and long-lasting durability
• OE Vane Configuration: Duplicates precise original equipment vane geometry for proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances: Processed at state-of-the-art machining facilities for consistent fitment and performance
• 100% Mill-Balanced: All vented rotors are electronically mill-balanced for smooth, vibration-free stops at any speed
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in and quieter stops
• Ready to Install: Processed dry and shipped dry — no degreasing or prep work needed

OEM Cross-Reference Part Numbers: 1644230512, 1644231212. Sold individually (1 rotor per package). The GeoSpec coating is designed to be safely swept away by the friction material during the bed-in process with no harmful effects on braking performance or pad wear.
