Dynamic Friction 4822-31238 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4822-31238 is a DFC GeoSpec® Coated Plain (Blank) Disc Brake Rotor engineered to deliver OEM-quality braking performance with superior corrosion protection. Designed as a direct-fit replacement, this rotor requires no modifications and installs using factory mounting points and hardware.

The signature GeoSpec® coating forms a durable, attractive silver-gray finish that outperforms conventional paint and zinc coatings in rust and corrosion resistance. Unlike oil-coated rotors, each GeoSpec rotor is processed dry, shipped dry, and is ready to install straight out of the box — no degreasing or additional preparation required. The coating is safely swept away by the friction material during normal bed-in with no harmful effects on braking performance.

Key Features:

• GeoSpec® full coating — completely coated inside and out for maximum corrosion protection before and after installation
• Premium G3000/G11H18 iron casting for superior strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available for precise fitment and consistent performance
• OE vane configuration to ensure proper and maximum heat dissipation
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter, smoother stops
• 100% mill-balanced using an electronic mill-balance process for vibration-free braking at any speed
• 100% inspected — each rotor passes a full inspection station verifying all critical attributes to OE specifications
• Plain/blank rotor surface — smooth design compatible with a wide range of OEM-spec brake pads
• No modifications required — direct OEM replacement form, fit, and function

DFC GeoSpec rotors are engineered and manufactured to duplicate precise original equipment vane configurations and fitment, making installation straightforward and ensuring proper braking characteristics from the first stop. Sold individually.
