The Dynamic Friction 4004-46042 is a GeoSpec Coated Slotted Brake Rotor Set engineered as a direct OEM replacement with enhanced corrosion protection and performance. Featuring DFC's proprietary GeoSpec® coating, these rotors form a durable silver-gray finish that outperforms conventional paint or zinc coatings in corrosion resistance — validated to withstand over 400 hours of salt spray testing.

Key Features:

• Ready to Install — processed dry and shipped dry, no pre-degreasing or cleaning required straight out of the box

• Premium G3000/G11H18 Cast Iron Construction — engineered for strength, stability, and long-lasting durability
• Slotted Rotor Surface — slots help evacuate heat, gas, and debris for consistent braking performance under demanding conditions
• CNC-Machined to Tight Tolerances — ensures precise fit and proper OEM form, fit, and function
• OE Vane Configuration — matches original equipment vane design for optimal heat dissipation
• 100% Precision Mill-Balanced — delivers smoother stops and zero vibration at any speed
• Non-Directional Brake Surface Finish — promotes faster break-in and quieter operation from the start
• 100% Electronically Inspected — each rotor is measured across 20+ critical attributes to confirm OE specifications are met

The DFC 4004-46042 set meets or exceeds OEM specifications, making it an ideal upgrade for drivers seeking reliable, long-lasting braking performance with a clean factory appearance. Compatible with normal commuting, performance street driving, towing, and off-road use.
