Dynamic Friction 4804-13026 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4804-13026 is a GeoSpec® fully coated plain disc brake rotor engineered as a direct OE replacement for passenger cars and light trucks. Built to match original equipment vane configurations and fitment tolerances, this rotor delivers reliable, quiet stopping performance right out of the box.

DFC's proprietary GeoSpec® coating applies a patented silver-gray finish completely inside and out, providing superior corrosion resistance compared to conventional zinc plating or paint. Importantly, the coating is formulated to avoid contaminating friction surfaces, ensuring a proper brake bed-in and consistent wear characteristics over the life of the rotor.

Key Features:

• Fully coated inside and out — GeoSpec® patented rust-prevention coating resists corrosion far better than zinc or conventional paint
• Premium G3000 cast iron construction — engineered for strength, stability, and long-lasting durability
• OE vane configuration — duplicates original equipment design for maximum heat dissipation
• CNC-machined to tight tolerances — ensures precise fitment and consistent performance
• 100% precision mill-balanced — promotes smoother stopping and eliminates vibration at any speed
• Non-directional surface finish — promotes faster break-in and smoother stops
• Ready to install — no pre-cleaning or degreasing required before installation
• Plain / smooth rotor style — ideal for OE-style replacement and everyday driving

The DFC GeoSpec rotor program covers more than 1,400 SKUs spanning foreign and domestic passenger cars and light truck applications, making it one of the most comprehensive coated rotor lines available. The 4804-13026 is sold individually and is designed for straightforward installation in a standard brake service.
