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 to improve brake pad bite and heat dissipation. This design helps reduce brake fade during demanding driving conditions, making it suitable for heavy-duty applications such as towing or hauling in Ford and Lincoln vehicles. The silver zinc coating on the rotor hat enhances corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This vented rotor features a 308 mm outside diameter and a 102.9 mm overall height, ensuring compatibility with specified Ford and Lincoln models. The drilled and slotted surface type improves water and debris evacuation from the braking surface, maintaining consistent friction. The rotor’s 5-lug bolt pattern with a 135 mm bolt circle diameter matches factory specifications for the Ford F-150, Expedition, and Lincoln Navigator. The zinc silver hat finish provides rust resistance, while the plain disc finish maintains a clean braking surface.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford F-150, Expedition, and Lincoln Navigator
• Improves heat dissipation to reduce brake fade during heavy braking or towing
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Restores proper rotor thickness and braking surface integrity

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 27.7 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify bolt hole alignment with the 5-lug, 135 mm bolt circle pattern on your vehicle. Use proper torque specifications for lug nuts to avoid rotor warping. This rotor is directional; install with the correct orientation for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 631-54170R rotor to meet OEM standards for fit and function on Ford and Lincoln vehicles. The rust-resistant zinc silver coating and vented design contribute to durability and consistent braking performance. While no specific warranty information is provided, this rotor is engineered to maintain structural integrity and braking efficiency under normal operating conditions.
