Detailed Product Features and Specifications

This Dynamite Friction rotor is part of the DFC Brake Rotor - Drilled and Slotted - Silver line, which focuses on delivering rotors with enhanced surface designs for improved braking efficiency. The drilled and slotted surface helps to evacuate gases, dust, and water from the braking surface, reducing brake fade and improving pad bite. The vented rotor construction allows for better airflow, which aids in heat dissipation during heavy braking.

The rotor’s zinc silver hat finish provides corrosion resistance, extending the rotor’s service life, especially in environments prone to rust. With a nominal thickness of 34 mm and a discard thickness of 32 mm, this rotor maintains structural integrity while providing a clear wear limit for safe replacement. The six bolt holes and matching stud/lug hole quantity ensure proper fitment and secure mounting on compatible Ford Bronco and Ranger models.

Applications and Problem Solving

• Replaces worn or warped rotors on Ford Bronco and Ranger vehicles
• Improves braking performance by reducing heat buildup and brake fade
• Helps prevent rust and corrosion with a protective zinc silver coating
• Enhances brake pad contact and debris removal with slotted and drilled design
• Maintains vehicle safety and stopping power under heavy load or off-road conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 32 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 139.7 mm bolt circle diameter and 13.2 mm bolt hole diameter. Proper torque specifications should be followed to secure the rotor firmly. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.
