DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction is designed to provide enhanced braking efficiency through a combination of drilled holes and precision slots. This design improves water and gas evacuation from the rotor surface, which helps maintain consistent braking performance. The vented rotor construction further aids in heat dissipation, making it suitable for heavy-duty applications such as those encountered by Dodge Ram trucks.

Detailed Product Description

This disc brake rotor features a directional surface pattern with both drilled holes and slots, which work together to improve pad bite and reduce brake fade by allowing gases and debris to escape. The rotor is vented, promoting airflow to dissipate heat generated during braking. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28.39 mm, ensuring a long service life before replacement is necessary. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rotor includes a rust resistant coating to protect against environmental damage. With eight bolt holes sized at 17 mm diameter and a bolt circle diameter of 165.1 mm, this rotor is designed to fit securely on compatible Dodge Ram models.

Applications and Problem Solving

• Improves braking performance for Dodge Ram 1500, 2500, and 3500 trucks
• Reduces brake fade during heavy towing or hauling
• Enhances heat dissipation to prevent rotor warping
• Minimizes rust and corrosion for longer rotor life
• Maintains consistent brake pad contact with directional drilled and slotted surface

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated by the manufacturer. Verify bolt hole alignment with the vehicle’s hub using the 8-bolt pattern and 165.1 mm bolt circle diameter. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 28.39 mm. Proper torque specifications should be followed to secure the rotor and avoid warping.

Quality Assurance

Dynamite Friction manufactures the DFC Geoperformance Rotor - Drilled and Slotted to meet or exceed OEM specifications for fitment and performance. The rust resistant coating and Geospec silver grey hat finish contribute to the rotor’s durability. Warranty information is available through Dynamite Friction and should be consulted for specific coverage details.
