About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to enhance braking performance by improving heat dissipation and reducing brake fade. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is designed for drivers who require reliable stopping power under demanding conditions, making it suitable for Dodge Durango and Jeep Grand Cherokee vehicles equipped with solid rotors.

Product Details and Specifications

This disc brake rotor features a solid construction with a 330 mm outside diameter and a 63.7 mm overall height, ensuring compatibility with specified Dodge and Jeep models. The rotor's surface is both drilled and slotted, which helps to evacuate gases and debris from the braking surface, maintaining consistent pad contact and reducing the risk of brake fade. The directional design of the braking surface optimizes performance by channeling heat and moisture away from the rotor. The zinc silver hat finish offers rust resistance, protecting the rotor from corrosion over time. With 5 bolt holes sized at 17 mm diameter and a bolt circle diameter of 127 mm, this rotor fits securely on compatible hubs.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Dodge Durango and Jeep Grand Cherokee
• Improves heat dissipation to reduce brake fade during heavy braking
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust and corrosion on rotor hats for longer service life
• Enhances braking consistency in wet or demanding driving conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 12.5 mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Verify bolt hole alignment with the vehicle hub using the 5-bolt, 127 mm bolt circle pattern. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.
