• Overall diameter of 305 mm and height of 63.5 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented rotor design that allows air to flow between the rotor surfaces, effectively reducing heat and minimizing brake fade during extended use. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water, improving brake pad contact and performance. The directional brake surface ensures optimal rotation alignment for enhanced braking efficiency.

The rotor features a plain disc finish combined with a zinc silver rust-resistant coating on the hat, providing corrosion protection and extending the rotor’s service life. With a nominal thickness of 26 mm and a discard thickness of 24.5 mm, this rotor meets precise wear specifications to maintain safe braking performance. The five bolt holes and stud/lug holes, each with a diameter of 15.3 mm and arranged on a 127 mm bolt circle diameter, ensure proper fitment and secure installation on compatible Jeep Grand Cherokee models.

About the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced heat dissipation and corrosion resistance. This product line combines drilled holes and slots on the rotor surface to improve braking response and reduce the risk of brake fade. The zinc silver coating on the rotor hat adds an extra layer of protection against rust, making these rotors suitable for vehicles exposed to various driving conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Jeep Grand Cherokee
• Improves brake cooling to reduce fade during heavy braking
• Helps eliminate brake noise caused by gas and dust buildup
• Addresses corrosion issues with rust-resistant coating
• Restores braking performance for safer vehicle operation

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify that the rotor thickness is within the specified nominal and discard limits before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Use proper torque specifications on the five lug bolts to secure the rotor firmly. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
