Detailed Product Features and Specifications

This Dynamite Friction rotor features a vented design that improves airflow to reduce heat buildup during braking, which is critical for heavy-duty applications like the Ford F-250 and F-350. The drilled and slotted surface helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing brake fade. The directional brake surface is engineered to optimize braking efficiency and rotor longevity.

The rotor’s hat is coated with a zinc silver finish to resist rust and corrosion, extending the service life of the part. The plain disc finish provides a smooth braking surface, while the eight bolt holes with a diameter of 14.94 mm and a bolt circle diameter of 165.1 mm ensure a secure and precise fit. The rotor’s nominal thickness is 31.62 mm, with a discard thickness of 29.97 mm, indicating when replacement is necessary to maintain safe braking performance.

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 delivering rotors with enhanced heat dissipation and improved braking response. This line combines drilled holes and slots on the rotor surface to help maintain clean contact between the brake pad and rotor, which is especially beneficial for trucks like the Ford F-250 and F-350 that often operate under heavy loads or in challenging conditions.

Applications and Problem Solving

• Reduces brake fade during heavy towing or hauling
• Improves braking performance in wet or dusty environments
• Helps prevent rotor warping caused by excessive heat
• Maintains consistent brake pad contact for smoother stops
• Resists corrosion to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor is installed on compatible Ford F-250 or F-350 models matching the specified bolt pattern and dimensions. Verify the rotor thickness before installation and replace if below the discard thickness of 29.97 mm. Proper torque specifications should be followed for the eight lug bolts to ensure secure mounting. It is recommended to inspect brake pads and other braking components during rotor replacement for optimal system performance.

Quality Assurance

Dynamite Friction manufactures the 631-54104L rotor to meet industry standards for durability and performance. The rust-resistant zinc silver coating on the hat and the vented rotor design contribute to long-term reliability. While no specific warranty information is provided, this rotor is engineered to maintain consistent braking performance for Ford F-250 and F-350 vehicles when installed and maintained properly.
