Dynamic Friction 4804-39024 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4804-39024 is a GeoSpec fully coated plain disc brake rotor engineered as a direct OEM-quality replacement for passenger cars and light trucks. Sold individually, this rotor delivers premium corrosion resistance and precision fitment right out of the box.

GeoSpec Coating Technology:

• Full-coverage rust protection — coated completely inside and out with a patented silver-gray paint finish that outperforms conventional paint and standard zinc coatings
• Ready to install — processed dry and shipped dry, requiring no cleaning or prep before installation, saving significant time on the brake job
• Brake-friendly formulation — the coating is safely swept away by friction material during bed-in with no harmful effects on pad or rotor surfaces

Precision Manufacturing:

• Cast from premium G3000 iron to duplicate OE vane configurations and ensure proper fitment
• CNC-machined to tight tolerances at state-of-the-art facilities
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter, smoother stops
• Vented rotors are 100% inspected for balance and corrected using an electronic mill-balance process when necessary

The DFC GeoSpec program covers more than 1,400 SKUs across foreign and domestic passenger car and light truck applications, making it one of the most comprehensive coated rotor programs available in the aftermarket.
