Dynamic Friction 9004-31049 Hi-Carbon Alloy GEOMET Coated Plain Brake Rotor Set

The Dynamic Friction Company (DFC) 9004-31049 is a Hi-Carbon Alloy GEOMET Coated plain (blank/smooth) disc brake rotor set engineered as a direct OE replacement. Designed to match the original equipment form, fit, and function, these rotors deliver reliable stopping power and long-lasting corrosion resistance right out of the box.

GEOMET® Coating Technology:

Each rotor receives a genuine GEOMET® finish applied across the entire rotor surface — including the hat, vanes, and cheeks — providing superior corrosion protection compared to conventional zinc or paint coatings. The GEOMET® coating is processed dry and shipped dry, requiring no degreasing before installation. It is safely and gradually swept away by the friction material during normal braking with no harmful effects.

Key Features:

• Hi-Carbon Alloy Iron Construction — High-carbon iron formulations including Molybdenum, Chromium, and Carbon enhance noise-dampening characteristics while improving thermal conductivity and overall durability
• Premium G3000/G11H18 Iron Casting — Engineered for superior strength, stability, and long service life
• 100% Precision Mill-Balanced — CNC-machined and mill-balanced for smooth, vibration-free stopping at any speed
• Fine-Turned Finish (1.6 RMS) — Non-directional surface finish promotes faster break-in and smoother stops
• OE Vane Configuration — Matches original equipment vane design for proper and maximum heat dissipation
• 100% Electronic Inspection — Each rotor passes a multi-point electronic inspection station measuring over 20 attributes to confirm OE specification compliance
• Ready to Install — No degreasing or additional surface preparation required
• Plain/Blank Design — Smooth rotor face for quiet, consistent everyday performance

Covered by DFC's limited warranty, the 9004-31049 rotor set is an ideal choice for drivers seeking OE-quality replacement brake rotors with premium corrosion protection and proven braking performance.
