Features of the DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black is part of Dynamite Friction’s DFC product line, which focuses on delivering rotors with enhanced surface designs for improved braking efficiency. The drilled and slotted pattern helps evacuate gases, dust, and water from the rotor surface, reducing brake fade and maintaining consistent friction. The vented rotor design further aids in heat dissipation, which is critical for heavy-duty applications like those found in Ford Super Duty trucks and the Excursion.

Technical Specifications and Design Details

This rotor has a nominal thickness of 38 mm and a discard thickness of 36 mm, ensuring a long service life before replacement is necessary. The rotor’s outside diameter measures 331 mm, with an overall height of 99.5 mm. It features eight bolt holes with a diameter of 16.2 mm arranged on a 170 mm bolt circle diameter, matching the stud/lug hole pattern for secure fitment. The zinc black hat finish provides corrosion resistance, complemented by a rust-resistant coating on the rotor surface. The directional surface type optimizes braking performance by channeling debris and heat away from the contact area.

Applications and Problem Solving

• Restores braking performance on Ford Excursion, F-250 Super Duty, and F-350 Super Duty vehicles
• Reduces brake fade during heavy towing or hauling
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust buildup for cleaner operation
• Enhances wet weather braking with drilled and slotted design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 36 mm before installation. Clean the rotor surface to remove any protective coatings or residues. Verify bolt hole alignment with the vehicle’s hub using the 8-bolt pattern and 170 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Black to meet or exceed OEM specifications for Ford Super Duty and Excursion models. The rust-resistant coating and zinc black hat finish contribute to long-term durability. Warranty details are provided by the manufacturer and should be confirmed at the time of purchase.
