Dynamic Friction 4802-31040 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4802-31040 is a GeoSpec fully coated plain (smooth/blank) disc brake rotor engineered to deliver OE-quality braking performance with superior corrosion resistance. Designed as a direct OEM replacement, this rotor is built to the same form, fit, and function as the original equipment part it replaces.

The signature GeoSpec® coating sets this rotor apart from conventional zinc-plated or painted alternatives. Applied fully inside and out, the durable silver-gray finish fights rust far more effectively than standard coatings. The coating is engineered to be safely swept away by the friction material during normal brake bed-in, with no harmful effects on pad or rotor surfaces — promoting a faster, more even break-in and quieter stops.

Each rotor arrives processed dry and ready to install — no solvent cleaning or prep work required, saving significant time and labor during installation.

Key Features:

• GeoSpec® full-coverage rust-prevention coating — applied inside and out for maximum corrosion protection
• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• OE vane configuration for proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available for precise fitment
• 100% precision cut and mill-balanced for smooth, vibration-free stopping at any speed
• Non-directional finish promotes faster brake pad bed-in and quieter, smoother stops
• 100% inspected — each rotor passes a final inspection station verifying all critical attributes meet OE specifications
• Plain/blank rotor face — smooth surface compatible with standard OEM-style brake pads
• Ready to install straight out of the box — no cleaning or prep required
• 1-Year Manufacturer Warranty

The Dynamic Friction 4802-31040 is part of DFC's GEO-KIT 4000 series, offering a reliable, cost-effective brake rotor solution for everyday passenger car and light truck applications.
