Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on delivering rotors with enhanced surface designs to improve braking efficiency and rotor longevity. This rotor’s drilled and slotted surface helps evacuate gases, dust, and water from the braking surface, reducing brake fade and improving pedal feel. The vented rotor construction promotes airflow to dissipate heat more effectively during heavy braking.

With a nominal thickness of 37.9 mm and a discard thickness of 36.4 mm, this rotor maintains structural integrity and safety standards throughout its service life. The zinc silver hat finish combined with a rust-resistant coating protects against corrosion, extending the rotor’s usable life in various driving environments. The rotor’s directional surface design ensures optimal performance when installed correctly.

Applications and Problem Solving

• Replaces worn or warped rotors on Ford F-250 Super Duty and F-350 Super Duty trucks
• Addresses brake fade caused by excessive heat during towing or heavy load conditions
• Improves braking response in wet or dusty environments by channeling away debris and moisture
• Reduces rotor surface cracking and extends rotor life through vented design
• Restores braking efficiency and pedal feel for safer vehicle operation

Installation Notes and Tips

• Ensure correct rotor orientation to match the directional slotted and drilled surface
• Verify bolt hole alignment with the 8-hole, 16 mm diameter pattern and 169.8 mm bolt circle diameter
• Inspect hub and mounting surfaces for cleanliness before installation to prevent runout
• Torque lug nuts to manufacturer specifications for Ford F-250 and F-350 Super Duty models
• Replace brake pads simultaneously to optimize rotor performance and longevity
