Dynamic Friction 633-74009L DFC Drilled Slotted Zinc Brake Rotor - Black Front Left

The Dynamic Friction Company 633-74009L is a premium drilled and slotted disc brake rotor finished in a black zinc coating. Part of DFC's 633 Series performance rotor line, this rotor is engineered to deliver confident, fade-resistant stopping power for demanding driving conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes promote heat dissipation and help expel gas, dust, and water from the rotor surface for consistent bite and reduced brake fade
• Slotted Grooves: Continuously sweep the brake pad surface to maintain a clean, fresh contact edge and improve wet-weather braking performance
• Black Zinc Finish: Corrosion-resistant black zinc coating protects the non-swept rotor surfaces and hat area from rust and environmental degradation
• Vented Construction: Internal vane venting maximizes airflow through the rotor for superior thermal management under repeated hard stops
• G3000 Castings: Manufactured from high-grade G3000 gray iron for strength, durability, and consistent friction characteristics
• OE-Style Fitment: Direct-fit replacement design requires no modifications for installation
• Quantity: Sold individually (1 rotor per package) — driver side (left)

Dynamic Friction Company's 633 Series drilled and slotted rotors are an ideal upgrade for drivers seeking improved braking performance over standard OE rotors. The black zinc finish provides lasting protection against corrosion while maintaining an aggressive, high-performance appearance behind the wheel.
