Product Line Details: StopTech Sport Slotted Disc Brake Rotors

The StopTech Sport Slotted Disc Brake Rotors line is designed to offer enhanced braking performance through advanced rotor features such as slotted surfaces and vented construction. This product line focuses on improving heat dissipation and brake pad bite, which helps maintain consistent braking under high-stress driving conditions. The 126.67042SR rotor fits within this line, providing Jeep Grand Cherokee owners with a rotor that balances durability and performance.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize airflow and reduce heat buildup during braking. The slotted surface helps to evacuate gases and debris from the pad surface, improving braking consistency. The rotor’s coated hat finish offers corrosion resistance, extending the rotor’s service life. With a floating disc mounting system, the rotor allows for slight movement to reduce stress and improve alignment with the brake pads. The rotor measures 305 mm in outside diameter and has a nominal thickness of 26 mm, with a discard thickness of 24.5 mm, ensuring it meets OEM specifications for the Jeep Grand Cherokee.

Applications and Problem Solving

• Replaces worn or warped rotors on Jeep Grand Cherokee models
• Reduces brake fade during extended or aggressive driving
• Improves heat dissipation to prevent rotor cracking
• Enhances braking performance in wet or dusty conditions
• Addresses corrosion issues with coated hat finish

Installation Notes and Tips

Ensure the rotor is compatible with your specific Jeep Grand Cherokee year and trim before installation. Clean the hub surface thoroughly to prevent rotor runout. Use proper torque specifications on the 5 lug bolts (15.3 mm diameter) to secure the rotor. Since bearings and ABS tone rings are not included, verify these components separately if needed. It is recommended to replace brake pads when installing new rotors to ensure optimal performance.
