Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize braking performance. This design helps reduce brake fade by allowing gases and heat to escape more efficiently, while the directional surface pattern ensures consistent pad contact. The zinc silver hat finish adds a layer of protection against rust, making these rotors suitable for vehicles exposed to various driving conditions.

Technical Specifications and Features

This disc brake rotor is a solid type with a plain disc finish and a zinc silver coated hat for enhanced durability. It features a 330 mm outside diameter and a 63.7 mm overall height, fitting precisely on vehicles requiring a 5-lug bolt pattern with 17 mm bolt hole diameter and 127 mm bolt circle diameter. The rotor’s nominal thickness is 14 mm, with a discard thickness of 12.5 mm, ensuring safe replacement intervals. The directional slotted and drilled surface improves braking efficiency by promoting better pad cleaning and heat dissipation.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Dodge Durango and Jeep Grand Cherokee models
• Helps reduce brake fade during heavy braking or towing conditions
• Improves braking response and pad bite with slotted and drilled design
• Resists rust and corrosion for longer service life in varied climates
• Maintains consistent braking performance under high heat conditions

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is within the specified nominal and discard limits to maintain braking safety. This rotor requires a 5-lug wheel hub with a 127 mm bolt circle diameter and 17 mm bolt hole diameter. Proper torque specifications should be followed when mounting to avoid rotor warping. It is recommended to replace brake pads simultaneously for optimal performance.
