Dynamic Friction 633-56004L DFC Drilled Slotted Zinc Disc Brake Rotor - Black

The Dynamic Friction Company (DFC) 633-56004L is a premium cross-drilled and slotted disc brake rotor finished in a black zinc coating for corrosion resistance and a clean, aggressive appearance. Part of DFC's 633 Series, this rotor is engineered to deliver upgraded stopping performance over standard OEM rotors while maintaining a direct-fit replacement design.

Manufactured from G3000/G11H18 specification cast iron, the rotor casting is precision-machined to tight tolerances to ensure proper fit, balance, and OE-equivalent dimensional accuracy. Every rotor in the 633 Series undergoes a 100% electronic inspection process measuring over 20 critical attributes before leaving the facility. Vented rotors are also electronically mill-balanced to eliminate vibration and pedal pulsation.

Key Features:

• Cross-drilled holes help dissipate heat buildup and reduce brake fade during aggressive or repeated stops
• Curved slots channel away gas, dust, and debris from the pad surface for consistent bite
• Black zinc coating protects against rust and corrosion, maintaining appearance between brake pad replacements
• G3000/G11H18 premium iron casting for strength, stability, and long service life
• Precision-machined to OE specifications for a direct, no-modification installation
• 100% electronically inspected and mill-balanced for vibration-free performance
• Driver-side (left) position — sold individually

The DFC 633-56004L is recommended for passenger car and light truck applications where drivers want improved braking responsiveness and thermal management over a standard replacement rotor. It is compatible with DFC's 4000 and 5000 series brake pad lines for a complete brake system upgrade.
