Dynamic Friction 4804-31034 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4804-31034 is a GeoSpec® Coated Plain (Smooth) Disc Brake Rotor engineered to deliver reliable, quiet, and long-lasting braking performance. Featuring DFC's proprietary GeoSpec coating, this rotor is fully coated inside and out with a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings — arriving clean, dry, and ready to install with no pre-degreasing required.

Key Features:

• GeoSpec® Full Corrosion Protection Coating: Patented silver-gray coating applied to the entire rotor — not just the hat — for superior rust resistance before and after installation
• Premium G3000/G11H18 Iron Casting: Engineered with high-grade iron for superior strength, consistency, stability, and long service life
• OE Vane Configuration: Original Equipment vane geometry ensures proper and maximum heat dissipation for fade-free performance
• CNC-Machined to Tight Tolerances: Precision machining and a non-directional surface finish promote faster, more even brake pad bed-in and quieter stops
• 100% Mill-Balanced: All vented rotors are electronically mill-balanced for smooth, vibration-free braking at any speed
• Ready to Install: Shipped dry — no cleaning or additional preparation needed, saving time during installation
• OEM Form, Fit, and Function: Designed as a direct replacement matching the same specifications as the original equipment rotor
• No Modifications Required: Direct bolt-on fitment with no drilling, cutting, or adapters needed

The DFC GeoSpec program covers over 1,400 SKUs for domestic and foreign passenger cars and light trucks, making it one of the most comprehensive coated rotor programs available. The 4804-31034 is quality tested for long-lasting performance and backed by a manufacturer warranty.
