Detailed Product Description

This StopTech rotor is part of the StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line, which is designed to provide enhanced braking performance for sport and street applications. The cross-drilled and slotted surface helps to evacuate gases, dust, and water from the braking surface, improving pad bite and reducing the risk of brake fade. The vented rotor design allows air to flow between the rotor faces, dissipating heat more effectively during aggressive driving or towing.

The rotor features a coated hat finish that protects against rust and corrosion, helping maintain structural integrity and appearance over time. The floating disc mounting system allows for slight movement between the rotor and hub, which can reduce stress and improve rotor lifespan. With a 5-lug bolt pattern and a 5-inch bolt circle diameter, this rotor is specifically designed for Dodge Durango and Jeep Grand Cherokee models, including the WK series.

Applications and Problem Solving

• Reduces brake fade during heavy braking or towing
• Improves braking response in wet or dusty conditions
• Minimizes rotor warping caused by heat buildup
• Helps maintain consistent brake pad contact and performance
• Prevents corrosion on the rotor hat for longer service life
