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 braking efficiency. This design helps to evacuate heat, water, and brake dust, which can accumulate during heavy use. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for heavy-duty applications such as the Ford F-250 and F-350 Super Duty trucks, where durability and consistent braking are critical.

Technical Specifications and Features

This disc brake rotor features a vented design with a directional surface that includes both drilled holes and slots. The rotor's nominal thickness is 38 mm, with a discard thickness of 36.4 mm, ensuring clear service limits. The rotor measures 347 mm in outside diameter and 115.6 mm in overall height. It includes eight bolt holes with a diameter of 14x1.5 mm and a bolt circle diameter of 170 mm, matching the stud/lug hole circle diameter for proper fitment. The rotor surface is finished plain, while the hat is coated in zinc silver for rust resistance.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford F-250 Super Duty and F-350 Super Duty
• Improves heat dissipation to reduce brake fade during heavy towing or hauling
• Helps prevent brake judder caused by uneven rotor surfaces
• Resists rust and corrosion for longer service life in harsh environments
• Maintains braking performance in wet conditions due to drilled and slotted design

Installation Notes and Tips

Ensure the rotor is compatible with your specific Ford F-250 or F-350 Super Duty model year and configuration before installation. Clean the hub surface thoroughly to prevent runout and ensure proper rotor seating. Torque all bolts to manufacturer specifications using the 14x1.5 bolt pattern and 8-bolt configuration. Because this rotor features a directional surface, install it according to the rotation direction indicated to maintain optimal braking performance.

Quality Assurance

Dynamite Friction manufactures the 631-54201L rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver coating on the rotor hat helps extend service life. While no specific warranty information is provided, this rotor is designed for durability and consistent braking performance on Ford Super Duty trucks.
