Power Stop - Rear Genuine Geomet Coated Rotor Product Line

The Power Stop - Rear Genuine Geomet Coated Rotor line focuses on providing rotors with a durable Geomet coating that resists rust and corrosion. This coating helps maintain rotor integrity over time, especially in environments prone to moisture and road salt exposure. The vented rotor design enhances heat dissipation, reducing the risk of brake fade during extended use. This product line is tailored for rear brake applications on select Dodge and Jeep vehicles, ensuring compatibility and performance.

Detailed Product Description

This disc brake rotor is specifically designed for rear brake systems on Dodge Durango and Jeep Grand Cherokee vehicles. The vented rotor construction allows air to flow between the rotor surfaces, improving cooling and reducing heat buildup during braking. The rotor's nominal thickness of 28.00 mm and discard thickness of 26.00 mm provide clear service limits for maintenance. The Geomet coating offers a protective layer against rust, which is critical for maintaining rotor lifespan and braking efficiency. With an outside diameter of 349.90 mm and a mounting bolt hole circle diameter of 127.00 mm, this rotor fits securely with the vehicle's hub assembly. The 5 lug hole configuration matches the factory specifications for these models.

Common Applications and Issues Addressed

• Replacement for worn or warped rear rotors on Dodge Durango and Jeep Grand Cherokee
• Corrosion prevention in areas with high humidity or road salt exposure
• Improved heat dissipation to reduce brake fade during towing or heavy braking
• Restoring proper rotor thickness to maintain braking performance and safety
• Addressing uneven rotor wear or scoring that affects brake pad contact

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is within the nominal range and above the discard thickness limit. Use proper torque specifications for the 5 lug bolts to secure the rotor. It is recommended to inspect brake pads and replace if worn to ensure optimal braking performance. After installation, perform a brake system test to confirm proper operation and absence of noise or vibration.

Quality Assurance and Warranty

Power Stop rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The Geomet coating provides additional protection against corrosion, contributing to longer rotor life. While specific warranty details are not provided, Power Stop products typically come with a limited warranty against defects in materials and workmanship.
