Dynamic Friction 4804-76034 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4804-76034 GeoSpec Coated Plain Brake Rotor delivers OE-quality stopping performance wrapped in a patented corrosion-resistant coating engineered specifically for the thermal and environmental demands of brake rotors. The signature silver-gray GeoSpec finish fights rust far better than conventional paint or zinc coatings, keeping the rotor protected on the shelf, during shipping, and throughout its service life on the vehicle.

Ready to Install — No Prep Required

Unlike bare or oil-coated rotors that require degreasing before installation, GeoSpec Coated rotors ship dry and install straight out of the box. The coating on the friction surfaces is safely swept away by the brake pads during the initial bed-in process, with no harmful effects on braking performance.

Key Features:

• Patented GeoSpec Coating — Durable silver-gray finish provides superior corrosion resistance over zinc and conventional paint coatings
• Premium G3000/G11H18 Iron Castings — High-grade iron formulation engineered for strength, stability, and long-term durability
• OE Vane Configuration — Matches original equipment vane geometry for proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances — Precision machining ensures consistent rotor thickness and runout for smooth, vibration-free braking
• Non-Directional Finish — Promotes faster, more even brake pad bed-in and quieter stops
• 100% Mill-Balanced — Every vented rotor is electronically mill-balanced and corrected as needed to eliminate vibration at any speed
• 100% OE Spec Inspection — Each rotor passes a full inspection station measuring all critical attributes before shipping
• Plain (Smooth) Style — Solid, unslotted, non-drilled design ideal for everyday street driving and OE replacement

The DFC GeoSpec program covers more than 1,400 SKUs across a wide range of foreign and domestic passenger cars and light trucks, making it one of the most complete coated rotor programs available. The 4804-76034 is engineered to meet the same form, fit, and function as the original equipment rotor it replaces.
