Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black from Dynamite Friction is designed specifically for the Ford F-350 Super Duty, ensuring precise fitment and optimal braking performance. The rotor’s vented construction allows air to flow between the rotor faces, helping to dissipate heat more effectively during heavy braking. The directional surface pattern combines drilled holes and slots to aid in gas and dust evacuation, reducing brake fade and improving pad bite.

The rotor’s nominal thickness is 38 mm, with a discard thickness of 36.4 mm, providing a clear service limit for safe operation. The hat section is finished with a zinc black coating to resist rust and corrosion, extending the rotor’s service life. With eight bolt holes measuring 13 mm in diameter and a bolt circle diameter of 156 mm, this rotor matches the factory specifications for the F-350 Super Duty’s braking system.

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