Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC product line, which focuses on delivering rotors with enhanced cooling and braking efficiency. This rotor is vented to improve airflow and reduce heat buildup during heavy braking. The drilled and slotted surface helps evacuate gases, dust, and water, contributing to consistent brake pad contact and reduced brake fade.

With a nominal thickness of 30 mm and a discard thickness of 28 mm, this rotor maintains structural integrity and safety standards throughout its service life. The rotor's overall height and diameter (98.5 mm and 326 mm respectively) are designed to match the exact specifications required for Ford Super Duty trucks and Excursion models. The zinc silver coating on the hat provides rust resistance, extending the rotor's durability in various driving conditions.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford Excursion, F-250 Super Duty, and F-350 Super Duty
• Improves heat dissipation to reduce brake fade during towing or heavy load conditions
• Helps maintain consistent braking performance in wet or dusty environments
• Addresses rotor surface damage such as scoring or cracking
• Restores proper brake rotor thickness and structural integrity

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28 mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Verify bolt hole alignment with the 8-hole, 170 mm bolt circle diameter pattern specific to Ford Excursion and Super Duty models. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to inspect brake pads and replace if worn to ensure optimal braking performance.
