The Dynamic Friction 4804-13020 is a DFC GeoSpec fully coated plain brake rotor engineered as a direct OE replacement. Constructed from premium G3000/G11H18 cast iron, this rotor is built to meet the same form, fit, and function as the original equipment part while delivering enhanced corrosion resistance and long-term durability.

GeoSpec® Coating Technology:

• Completely coated inside and out with a high-quality rust-prevention coating that outperforms conventional paint and zinc coatings
• Forms a durable, attractive silver-gray finish that protects the rotor before and after installation

• Processed and shipped dry — ready to install straight out of the box with no pre-cleaning or degreasing required

Precision Machining & Performance:

• CNC-machined to the tightest tolerances available for consistent, reliable performance
• 100% precision mill-balanced to eliminate vibration and deliver smooth, quiet stops at any speed
• Non-directional rotor finish promotes faster, more even brake pad bed-in
• Original Equipment (OE) vane configuration ensures maximum and proper heat dissipation
• 100% inspected at a dedicated quality control station measuring all critical attributes

Plain / Smooth Rotor Style:

• Smooth rotor face ideal for normal daily commuting and OE-replacement applications
• Engineered to deliver quiet, vibration-free stops with low noise levels
• Backed by a 1-year manufacturer warranty
