DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on delivering rotors with enhanced surface features designed to improve braking efficiency. The drilled and slotted surface pattern helps evacuate gases, dust, and water from the braking surface, which is critical for maintaining consistent stopping power. The vented rotor design further aids in heat dissipation, making this rotor suitable for heavy-duty applications such as those encountered by Ford Super Duty trucks.

Detailed Product Description

This disc brake rotor features a directional surface type combining both drilled holes and slots, which work together to reduce brake fade and improve pad bite. The rotor is vented, allowing air to flow between the rotor faces to dissipate heat more effectively during braking. The rotor’s nominal thickness is 38 mm, with a discard thickness of 36.4 mm, ensuring a long service life before replacement is necessary. The hat section is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. The rotor includes eight bolt holes with a diameter of 16.2 mm and a bolt circle diameter of 170 mm, designed to fit securely on compatible Ford F-250 and F-350 Super Duty models.

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 heavy towing or hauling
• Improves braking performance in wet or dusty conditions through drilled and slotted design
• Prevents rust and corrosion on braking surfaces with rust-resistant coating
• Maintains consistent braking feel and reduces vibration from rotor surface irregularities

Installation Notes and Tips

Ensure the rotor is installed on compatible Ford F-250 Super Duty or F-350 Super Duty models matching the bolt pattern and dimensions. Verify the rotor thickness before installation; replace if below the discard thickness of 36.4 mm. Clean the rotor surface to remove any protective coatings or residues before mounting. Properly torque all lug nuts to manufacturer specifications to avoid rotor warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures the DFC Geoperformance Rotor - Drilled and Slotted to meet industry standards for durability and performance. The rotor includes a rust-resistant coating and a precision-machined surface to ensure consistent braking. While specific warranty details are not provided, Dynamite Friction products typically adhere to quality control processes to support reliable operation in heavy-duty applications.
