Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that feature both drilled holes and slots on the braking surface. This design helps to reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The black zinc coating on the hat area provides additional protection against rust, making these rotors suitable for demanding environments and heavy-duty applications.

Technical Specifications and Features

This vented disc brake rotor has a nominal thickness of 30 mm and a discard thickness of 28.5 mm, ensuring a long service life before replacement is necessary. The rotor’s outside diameter measures 325 mm, with an overall height of 131.5 mm. It features a directional surface type with slotted and drilled patterns to optimize braking efficiency and maintain consistent pad contact. The rotor is designed with an 8-bolt hole pattern, each hole measuring 16.4 mm in diameter, compatible with Chevrolet Express 3500, GMC Savana 3500, and various 3500 series Silverado and Sierra models.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Chevrolet Silverado 3500 and GMC Sierra 3500 trucks
• Improves heat dissipation to reduce brake fade during heavy towing or hauling
• Helps prevent rust and corrosion with zinc black hat finish and rust-resistant coating
• Enhances braking performance in wet or debris-prone conditions with drilled and slotted surface
• Maintains consistent braking feel and pad contact with directional rotor design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28.5 mm before installation. The rotor fits vehicles with an 8-lug bolt pattern and 16.4 mm bolt hole diameter; verify compatibility with your specific Chevrolet or GMC 3500 series model. Clean the hub surface before mounting to prevent runout. Use proper torque specifications on lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.
