Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is specifically designed for Jeep Commander and Grand Cherokee vehicles requiring a reliable and performance-oriented rotor. The rotor’s vented construction with straight vanes improves airflow, helping to maintain optimal operating temperatures during heavy braking. The cross-drilled and slotted surface enhances pad bite and helps evacuate brake dust, water, and gases, which can otherwise reduce braking efficiency. The coated hat finish protects the rotor’s center section from rust and corrosion, ensuring longevity. With a floating disc mounting system, this rotor accommodates thermal expansion, reducing the risk of warping under extreme conditions.

Common Applications and Problem Solving

• Reduces brake fade during aggressive driving or towing
• Improves braking response in wet or dusty conditions
• Minimizes rotor warping caused by heat buildup
• Prevents corrosion on the rotor hat for extended service life
• Enhances overall braking performance for Jeep Commander and Grand Cherokee models

Installation Notes and Tips

• Ensure rotor discard thickness (1.122 inches / 28.500 mm) is not exceeded before installation
• Verify compatibility with vehicle’s 5 lug hole pattern and mounting bolt circle diameter of 126.800 mm (4.992 inches)
• Use proper torque specifications for mounting bolts to avoid rotor distortion
• Check for ABS tone ring compatibility; this rotor does not include an ABS tone ring
• Inspect brake pads and calipers during installation for optimal performance
