This product line is suitable for drivers seeking improved brake response and durability on vehicles like the Jeep Grand Cherokee.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to promote airflow and heat dissipation. The rotor’s overall height measures 63.5 mm (2.5 inches), and it includes a coated hat finish to resist corrosion and extend service life. The rotor is designed with a floating disc mounting system, which allows for slight movement to reduce stress and improve braking consistency. It has a center hole diameter of 72 mm (2.835 inches) and five lug holes sized at 15.3 mm (0.602 inches) diameter on a 127 mm (5 inch) bolt circle.

Applications and Problem Solving

• Reduces brake fade during heavy braking or towing
• Improves heat dissipation for consistent brake performance
• Minimizes brake dust and gas buildup on rotor surface
• Enhances braking response for Jeep Grand Cherokee models
• Resists corrosion with coated hat finish for longer rotor life

Installation Notes and Tips

Ensure compatibility with your Jeep Grand Cherokee by verifying lug pattern and rotor dimensions before installation. The floating disc mounting requires proper alignment to avoid uneven wear. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Clean the rotor surface before installation to remove any protective coatings or residues.
