Details on the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that feature both drilled holes and slots on the braking surface. This design helps to reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The black zinc coating on the hat area adds a layer of rust resistance, making it suitable for vehicles exposed to varying weather conditions. This rotor line is tailored for drivers who require consistent braking performance on Jeep and Ram trucks and SUVs.

Product Description and Specifications

This vented disc brake rotor is engineered with a 378 mm outside diameter and a nominal thickness of 30 mm, ensuring compatibility with specific Jeep and Ram models including the Grand Wagoneer, Grand Wagoneer L, Wagoneer, Wagoneer L, and Ram 1500. The rotor features a directional surface with drilled holes and slots to enhance braking response and reduce heat buildup during heavy use. The zinc black hat finish and rust resistant coating protect against corrosion, extending the rotor's service life. With six bolt holes sized at 17 mm diameter and a bolt circle diameter of 139.7 mm, this rotor matches factory mounting specifications precisely.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Jeep Grand Wagoneer and Ram 1500 models
• Improves braking performance under heavy load or towing conditions
• Reduces brake fade caused by excessive heat buildup
• Helps eliminate brake noise and vibration from uneven rotor surfaces
• Protects against rust and corrosion in humid or wet environments

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28.4 mm before installation. Clean the rotor surface to remove any protective coating residue prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 6-bolt pattern and 139.7 mm bolt circle diameter. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 633-40125R rotor to meet OEM standards for fit and function. The rust resistant coating and zinc black hat finish contribute to long-term durability. While no specific warranty information is provided, this rotor is designed to maintain consistent braking performance and resist premature wear when installed and maintained according to vehicle manufacturer guidelines.
