Detailed Product Description

The 631-54157L rotor from Dynamite Friction’s DFC Brake Rotor - Drilled and Slotted - Silver line is designed specifically for heavy-duty Ford trucks such as the F-250 Super Duty and F-350 Super Duty. This rotor features a vented design that helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during demanding driving conditions. The drilled and slotted surface improves water and debris evacuation, maintaining consistent braking performance in wet or dirty environments. The directional brake surface ensures optimal pad contact and braking efficiency.

The rotor’s hat is finished in zinc silver, providing a rust-resistant coating that extends the rotor’s service life by protecting against corrosion. With a nominal thickness of 38 mm and a discard thickness of 36 mm, this rotor meets strict durability standards. The eight bolt holes with a 16.2 mm diameter and a 170 mm bolt circle diameter ensure precise fitment and secure mounting on compatible Ford Super Duty models.

Applications and Problem Solving

• Replaces worn or warped rotors on Ford F-250 Super Duty and F-350 Super Duty trucks
• Addresses brake fade caused by excessive heat during towing or heavy loads
• Improves braking performance in wet or muddy conditions with slotted and drilled design
• Prevents rust and corrosion on brake components for longer service intervals
• Restores smooth and consistent braking response for safer driving

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 36 mm before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Use the correct torque specifications for the eight 16.2 mm bolt holes to secure the rotor firmly. The directional surface requires installation in the correct rotation direction to maintain optimal braking performance. Always inspect brake pads and hardware during rotor replacement for best results.
