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 precision slots to improve braking efficiency and rotor longevity. The silver zinc coating on the rotor hat provides corrosion resistance, helping maintain structural integrity and appearance over time. This product line is designed to meet the specific braking demands of off-road and street-driven Jeep Wrangler vehicles.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. The directional slotted and drilled surface improves pad bite and helps channel away water, dust, and gases, which can degrade braking performance. The rotor measures 330 mm in outside diameter and 56 mm in height, with a nominal thickness of 24 mm and a discard thickness of 22.4 mm, ensuring it meets OEM standards for durability and safety. The zinc silver finish on the rotor hat and rust-resistant coating extend the rotor's service life by protecting against corrosion. It features five bolt holes with a 17 mm diameter and a bolt circle diameter of 127 mm, matching Jeep Wrangler specifications precisely.

Applications and Problem Solving

• Replacement rotor for worn or warped Jeep Wrangler brake rotors
• Improves heat dissipation to reduce brake fade during heavy use
• Enhances braking performance in wet or dusty conditions with slotted and drilled design
• Prevents rust and corrosion on rotor hats for longer service life
• Maintains consistent braking feel and safety on off-road and street driving

Installation Notes and Tips

Ensure the rotor is compatible with your Jeep Wrangler model before installation. Clean the hub surface thoroughly to prevent rotor runout. Use proper torque specifications on the 5 lug bolts to secure the rotor. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 22.4 mm.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit, form, and function.
