Detailed Product Features and Specifications
This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering rotors with enhanced surface designs to improve braking efficiency. The drilled and slotted surface helps evacuate gases, dust, and water from the braking surface, reducing the risk of brake fade and maintaining consistent friction. The vented rotor construction allows air to flow between the rotor faces, further aiding in heat dissipation during heavy braking.
The rotor's directional surface is engineered to optimize braking performance by channeling debris away from the pad contact area. The rotor measures 360 mm in outside diameter and 53 mm in overall height, with a center hole diameter of 72 mm. It features a 5-lug bolt pattern with a bolt circle diameter of 126.8 mm and bolt hole diameter of 16.3 mm, ensuring proper fitment on compatible Jeep Grand Cherokee models. The rotor's nominal thickness is 32 mm, with a discard thickness of 31.8 mm, indicating when replacement is necessary.
Applications and Problem Solving
- Improves braking performance for Jeep Grand Cherokee vehicles under heavy load or towing conditions
- Reduces brake fade caused by heat buildup during aggressive driving or mountainous terrain
- Minimizes brake dust accumulation and water interference for consistent stopping power
- Prevents rust and corrosion on rotor surfaces to extend service life
- Maintains structural integrity with vented design to avoid warping and uneven wear
Installation Notes and Tips
Ensure the rotor is compatible with your specific Jeep Grand Cherokee model year and trim before installation. Clean the rotor surface to remove any protective coating or residue prior to mounting. Use proper torque specifications for the 5-lug bolt pattern to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance and rotor longevity.
