Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted by Dynamite Friction is a vented disc brake rotor designed to meet the demands of heavy-duty Ford trucks such as the Excursion, F-250 Super Duty, and F-350 Super Duty. Featuring a directional surface with both drilled holes and slots, this rotor improves brake pad bite and helps evacuate gases, dust, and water from the braking surface. The vented design enhances airflow, reducing heat buildup and minimizing brake fade during extended use.

Constructed with a nominal thickness of 38 mm and a discard thickness of 36 mm, this rotor maintains structural integrity under heavy braking conditions. The rotor’s hat is finished in Geospec silver grey, providing additional corrosion resistance, complemented by a rust resistant coating on the disc surface. The rotor includes eight bolt holes with a diameter of 16.2 mm and a bolt circle diameter of 170 mm, ensuring precise fitment on compatible Ford models.

About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted product line focuses on delivering rotors with enhanced braking performance through advanced surface treatments. The drilled and slotted design improves heat dissipation and pad cleaning, which is particularly beneficial for heavy-duty applications. This line is engineered to provide reliable stopping power and durability for demanding driving conditions.

Common Applications and Problem Solving

• Reduces brake fade during heavy towing or hauling
• Improves braking response in wet or dusty conditions
• Minimizes rotor warping caused by excessive heat
• Prevents rust and corrosion on braking surfaces
• Maintains consistent braking performance under heavy load

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 prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 170 mm bolt circle diameter and 16.2 mm bolt hole diameter. Proper torque specifications should be followed to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures the 830-54174R rotor to meet industry standards for durability and performance. The rust resistant coating and Geospec silver grey hat finish contribute to extended rotor life. While no specific warranty information is provided, the product is designed for reliable operation on Ford Excursion, F-250 Super Duty, and F-350 Super Duty vehicles.
