Details on 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 provide enhanced braking performance through improved heat dissipation and surface design. The drilled and slotted features help reduce brake fade by allowing gases and debris to escape, while the vented rotor design further aids in cooling. This product line is tailored for drivers seeking reliable stopping power and rotor durability on performance-oriented Chrysler and Dodge vehicles.

Technical Specifications and Features

This rotor features a vented design with an overall diameter of 320 mm and a height of 67.4 mm, ensuring compatibility with specified Chrysler and Dodge models. The directional slotted and drilled surface improves braking efficiency by maintaining cleaner pad contact and reducing heat buildup. The zinc silver coating on the hat provides rust resistance, extending rotor life in various driving conditions. The rotor’s bolt pattern includes five 16.7 mm diameter holes on a 115 mm bolt circle, matching factory specifications for secure fitment.

Applications and Problem Solving

• Compatible with Chrysler 300, Dodge Challenger, Charger, and Magnum models requiring vented disc brake rotors
• Addresses brake fade caused by excessive heat during aggressive driving or towing
• Helps reduce brake dust and debris accumulation on rotor surface
• Improves braking response and consistency under varied driving conditions
• Prevents premature rotor corrosion with rust-resistant coating

Installation Notes and Tips

Ensure the rotor is installed on vehicles with matching bolt hole patterns and dimensions as specified. The directional surface requires correct orientation for optimal performance; verify the rotor’s directional arrows align with wheel rotation. Check rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 22 mm and is above the discard thickness of 20.5 mm. Proper torque specifications should be followed when securing the rotor to avoid warping.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM standards for fit and function. The rust-resistant zinc silver hat finish contributes to long-term durability. While no specific warranty information is provided, the rotor’s design and materials support consistent braking performance and corrosion resistance for Chrysler and Dodge vehicles equipped with this part number 631-39018L.
