Detailed Product Features and Specifications

This Dynamite Friction DFC Brake Rotor is designed specifically for Jeep Wrangler models, ensuring proper fit and function. The rotor's surface combines drilled holes and slots arranged directionally to help evacuate gases, dust, and water from the braking surface, which can improve brake pad contact and reduce fade. The rotor has a nominal thickness of 14 mm and a discard thickness of 12.4 mm, indicating when replacement is necessary to maintain safe braking performance.

The rotor's hat is finished with a zinc black coating that provides rust resistance, extending the rotor's service life in harsh environments. It features five bolt holes with a diameter of 17 mm and a bolt circle diameter of 127 mm, matching the Jeep Wrangler's wheel hub specifications. The overall outside diameter measures 342 mm, with a height of 76.5 mm and a center hole diameter of 72 mm, ensuring precise alignment and fitment.

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

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with a corrosion-resistant black zinc finish on the hat. This product line is designed to provide enhanced heat dissipation and improved braking consistency, particularly for vehicles like the Jeep Wrangler that may encounter off-road or heavy-duty driving conditions. The directional surface pattern is engineered to optimize brake pad contact and reduce the risk of brake fade.

Applications and Problem Solving

• Improves braking performance in wet or muddy conditions by channeling water away from the rotor surface
• Reduces brake fade during extended or heavy braking by enhancing heat dissipation
• Prevents rust and corrosion on the rotor hat for longer service life
• Maintains consistent brake pad contact through directional slot and drill design
• Ensures proper fitment and alignment for Jeep Wrangler brake systems

Installation Notes and Tips

When installing the Dynamite Friction 633-42042L rotor on a Jeep Wrangler, ensure the rotor is mounted with the directional surface pattern oriented correctly according to the vehicle’s rotation. Verify that the rotor thickness is above the discard thickness of 12.4 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to brake pad installation. Use proper torque specifications for the five lug bolts to secure the rotor firmly.
