Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking efficiency and rotor cooling. The black zinc-coated hat finish provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of off-road and street driving, making it suitable for Jeep CJ5, CJ7, and Scrambler vehicles requiring reliable and consistent braking performance.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The directional surface pattern, featuring both drilled holes and slots, helps evacuate gases, dust, and water from the braking surface, improving pad bite and reducing brake fade. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20.7 mm, ensuring safe replacement intervals. The rotor’s bolt pattern includes five holes with a diameter of 16.5 mm and a bolt circle diameter of 139.7 mm, matching the factory specifications for Jeep CJ5, CJ7, and Scrambler models. The zinc black hat finish and rust-resistant coating protect against corrosion, maintaining rotor integrity over time.

Applications and Problem Solving

• Restores braking performance on Jeep CJ5, CJ7, and Scrambler vehicles
• Reduces brake fade caused by overheating during heavy use
• Improves water and debris evacuation for consistent braking in wet or off-road conditions
• Prevents rust and corrosion on rotor hats for longer service life
• Ensures proper fitment and alignment with factory bolt pattern and dimensions

Installation Notes and Tips

When installing the Dynamite Friction 633-42017L rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the directional pattern is oriented correctly to match the vehicle’s rotation direction. Use the factory-specified torque settings for the five lug bolts with 16.5 mm diameter holes. Inspect brake pads and calipers for wear or damage during installation to maintain optimal braking performance.
