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

The DFC Brake Rotor - Drilled and Slotted - Black product line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to improve brake pad bite and reduce heat buildup. The black zinc-coated hat finish provides corrosion resistance, extending rotor life. This line is designed to meet the demands of heavy-duty trucks like the Dodge Ram series, offering a balance of durability and performance.

Detailed Product Description

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps dissipate heat generated during braking. The directional surface pattern, featuring both drilled holes and slots, aids in removing brake dust, gases, and water from the rotor surface, improving braking consistency. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28.39 mm, ensuring a clear service life indicator. The zinc black hat finish and rust-resistant coating protect against corrosion, which is critical for vehicles exposed to harsh environments. With eight bolt holes sized at 17 mm diameter and a bolt circle diameter of 165.1 mm, this rotor fits securely on compatible Dodge Ram models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Dodge Ram 1500, 2500, and 3500
• Improves heat dissipation to reduce brake fade during heavy towing or hauling
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps maintain consistent braking performance in wet or dusty conditions
• Prevents rust and corrosion-related rotor degradation

Installation Notes and Tips

Ensure the rotor is installed on compatible Dodge Ram models with the correct bolt pattern (8 bolts, 17 mm diameter, 165.1 mm bolt circle). Verify the rotor thickness before installation; replace if below the discard thickness of 28.39 mm. Clean the rotor surface and hub mounting area to prevent uneven contact. Use proper torque specifications for lug nuts to avoid rotor warping. This rotor is directional, so install with the correct orientation for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet industry standards for durability and performance. The rust-resistant coating and zinc black hat finish contribute to long-term reliability. While no specific warranty information is provided, the rotor’s design and materials support consistent braking performance for Dodge Ram 1500, 2500, and 3500 vehicles.
