Detailed Product Description

The 830-42003R rotor from Dynamite Friction is part of the DFC Geoperformance Rotor - Drilled and Slotted line, designed specifically to meet the braking demands of Jeep Grand Cherokee drivers. The rotor’s vented construction allows air to flow between the rotor faces, reducing heat and minimizing brake fade during extended use. The directional surface features both drilled holes and slots, which help evacuate gases, dust, and water from the braking surface, improving pad bite and overall braking consistency.

Finished with a rust resistant coating and a Geospec silver grey hat finish, this rotor offers enhanced protection against corrosion, extending the service life of the part. The rotor measures 350 mm in outside diameter and 68.4 mm in overall height, with a nominal thickness of 28 mm and a discard thickness of 27.85 mm, ensuring it meets precise fitment and performance standards. The 5-bolt hole pattern with 16.3 mm diameter holes and a 127 mm bolt circle diameter matches the Jeep Grand Cherokee’s specifications for a secure fit.

Applications and Problem Solving

• Replaces worn or warped rotors on Jeep Grand Cherokee models
• Addresses brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions with slotted and drilled design
• Prevents rust and corrosion on braking surfaces
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor surface is clean and free of any contaminants before installation. Verify that the rotor thickness is within the specified nominal and discard limits to maintain braking safety. Use proper torque specifications for the 5-bolt pattern to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to optimize braking performance.

Quality Assurance

Dynamite Friction manufactures the 830-42003R rotor to meet OEM standards for fit and function on Jeep Grand Cherokee vehicles. The rust resistant coating and vented design contribute to long-term durability. Warranty information is available from the manufacturer and should be consulted for specific coverage details.
