Designed specifically for Ford Excursion, F-250 Super Duty, and F-350 Super Duty models, this vented disc brake rotor offers enhanced heat dissipation and consistent stopping power.

• Directional drilled and slotted surface for improved brake pad bite and heat management
• Vented rotor design to reduce brake fade during heavy-duty use
• Rust-resistant zinc silver hat finish for extended durability
• Nominal thickness of 38 mm with a discard thickness of 36 mm for safe replacement intervals
• Eight bolt holes with 16.2 mm diameter and 170 mm bolt circle diameter for precise fitment
• Overall diameter of 331 mm and height of 99.5 mm to match factory specifications

Detailed Product Description

This Dynamite Friction DFC Brake Rotor features a directional surface that is both drilled and slotted, designed to optimize braking efficiency by allowing gases and debris to escape while maintaining consistent pad contact. The vented rotor construction helps dissipate heat more effectively, reducing the risk of brake fade during demanding driving conditions common in Ford Excursion, F-250 Super Duty, and F-350 Super Duty trucks. The rotor’s zinc silver hat finish provides corrosion resistance, extending the rotor’s service life in various environments.

The rotor’s dimensions, including an outside diameter of 331 mm and an overall height of 99.5 mm, ensure compatibility with the specified Ford models. The eight bolt holes with a 16.2 mm diameter and a 170 mm bolt circle diameter align with factory mounting points for straightforward installation. The nominal thickness of 38 mm and discard thickness of 36 mm provide clear guidelines for maintenance and replacement.

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

The DFC Brake Rotor - Drilled and Slotted - Silver product line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish. This line is designed to improve braking performance by enhancing heat dissipation and maintaining clean pad surfaces, which is particularly beneficial for heavy-duty trucks like the Ford Excursion and Super Duty series. The silver zinc coating on the rotor hat adds an extra layer of protection against rust, making these rotors suitable for long-term use in various driving conditions.

Applications and Problem Solving

• Reduces brake fade during towing or heavy load conditions on Ford F-250 and F-350 Super Duty trucks
• Improves braking response and pad bite on Ford Excursion models
• Minimizes rotor surface glazing and pad deposits through slotted and drilled design
• Prevents premature rotor corrosion with rust-resistant coating
• Maintains structural integrity under high heat with vented rotor design

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is above the discard thickness of 36 mm to maintain safe braking performance. Use the correct torque specifications for the eight 16.2 mm bolt holes to secure the rotor properly. This rotor is directional; confirm the correct orientation during installation to optimize braking efficiency.

Quality Assurance

Dynamite Friction manufactures the 631-54174L rotor to meet or exceed OEM specifications for Ford Excursion, F-250 Super Duty, and F-350 Super Duty vehicles. The rust-resistant zinc silver finish and vented design contribute to durability and consistent performance. While no specific warranty information is provided, the rotor’s design and materials align with industry standards for quality and reliability.
