DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to optimize brake pad contact and heat dissipation. This product line is designed to meet the demands of trucks like the Ford F-150, where enhanced braking performance and rotor durability are critical. The directional surface pattern helps channel gases and debris away from the braking surface, contributing to consistent brake feel and reduced fade.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor faces to dissipate heat more effectively during braking. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring a clear service limit for safe operation. The rotor’s outside diameter measures 336 mm, with an overall height of 45 mm. It features six bolt holes with a diameter of 15.8 mm arranged on a 135 mm bolt circle diameter, matching the Ford F-150’s hub specifications. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rotor surface is coated with a rust-resistant layer to help prevent corrosion over time.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Ford F-150 trucks
• Improves heat dissipation to reduce brake fade during heavy towing or hauling
• Slotted and drilled design helps maintain consistent braking performance in wet or dusty conditions
• Rust resistant coating extends rotor life in harsh environments
• Directional surface pattern aids in debris removal and brake pad cleaning

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective coatings or oils prior to mounting. Verify bolt hole alignment with the Ford F-150 hub using the 135 mm bolt circle diameter and six 15.8 mm bolt holes. 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

Dynamite Friction manufactures the 830-54231L rotor to meet OEM specifications for the Ford F-150. The rust resistant coating and Geospec silver grey hat finish contribute to long-term durability. While no specific warranty information is provided, Dynamite Friction products are engineered for consistent performance and reliability in demanding automotive applications.
