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 combine drilled holes and slots with a silver zinc coating to resist corrosion. This product line is designed to provide consistent braking performance while reducing rotor surface heat and preventing rust buildup. The vented rotor design further aids in heat dissipation, making it suitable for heavy-duty applications such as those found in Dodge Ram trucks.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 35.5 mm and a discard thickness of 34 mm, ensuring a long service life before replacement is necessary. The rotor's surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water from the braking surface, improving pad contact and reducing brake fade. The rotor is vented, allowing air to flow between the rotor faces to dissipate heat more effectively during braking.

The rotor's hat is finished with a zinc silver coating that provides rust resistance, extending the rotor's durability in various weather conditions. It includes eight bolt holes with a diameter of 16.9 mm and a bolt circle diameter of 165.1 mm, matching the stud/lug hole pattern for secure installation on compatible Dodge Ram models. The overall diameter of 353 mm and height of 101.9 mm are designed to meet OEM specifications for proper fit and function.

Applications and Problem Solving

• Replacement for worn or warped rotors on Dodge Ram 1500, 2500, and 3500
• Improves braking performance by reducing heat buildup and brake fade
• Helps prevent rust and corrosion on braking surfaces
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Enhances pad bite and braking consistency in wet or dusty conditions

Installation Notes and Tips

• Ensure compatibility with Dodge Ram 1500, 2500, or 3500 before installation
• Check rotor thickness and discard limits to confirm replacement timing
• Clean mounting surfaces and torque bolts to manufacturer specifications
• Inspect brake pads and hardware during rotor replacement for optimal performance
• Follow directional rotor installation instructions to maintain proper braking function
