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 heat dissipation and helps reduce brake fade under demanding conditions. The directional surface pattern further aids in channeling gases and debris away from the rotor surface, maintaining consistent braking performance. The rust-resistant coating and Geospec silver grey hat finish contribute to corrosion resistance and long-term durability.

Detailed Product Description

This disc brake rotor features a vented design with an outside diameter of 352.5 mm and an overall height of 131 mm, suitable for heavy-duty applications on Dodge Ram 1500, 2500, and 3500 trucks. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28.39 mm, ensuring a reliable service life before replacement is necessary. The rotor includes eight bolt holes, each 17 mm in diameter, arranged on a 165.1 mm bolt circle diameter, matching the stud/lug hole pattern for secure fitment. The directional drilled and slotted surface enhances braking by improving heat dissipation and reducing brake dust buildup, while the vented rotor design helps maintain optimal operating temperatures during heavy braking.

Applications and Problem Solving

• Improves braking performance for Dodge Ram 1500, 2500, and 3500 trucks
• Reduces brake fade during heavy or prolonged braking
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes rust and corrosion with protective coating
• Maintains consistent braking response under demanding conditions

Installation Notes and Tips

Ensure the rotor is installed on compatible Dodge Ram models as specified. Verify bolt hole alignment with the vehicle’s hub using the 8-bolt, 17 mm diameter pattern on a 165.1 mm bolt circle diameter. Clean the rotor surface before installation to remove any protective coatings or residues. Proper torque specifications should be followed for lug nuts to avoid rotor damage or uneven wear. Directional rotors must be installed with the correct rotation direction for optimal performance.
