Detailed Product Description

This Power Stop rotor is part of the Power Stop - Rear Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating offers enhanced rust resistance compared to standard rotors, helping to maintain rotor integrity and appearance over time. The vented disc design improves heat dissipation during braking, reducing the risk of brake fade under heavy use. With precise dimensions including a nominal thickness of 1.50 inches and an outside diameter of 14.37 inches, this rotor is engineered to meet the exact specifications required for the Ram 3500 rear brake system.

Applications and Problem Solving

• Replacement for worn or warped rear disc brake rotors on Ram 3500 trucks
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust and corrosion that can reduce rotor lifespan
• Improves braking consistency under heavy load or towing conditions
• Restores proper rotor thickness to maintain safe braking performance

Installation Notes and Tips

Ensure the rotor mounting surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 1.43 inches (36.40 mm) to maintain safety standards. Use the correct torque specifications for the 8 lug bolts on the 6.14-inch bolt circle diameter. It is recommended to inspect brake pads and hardware during rotor replacement to ensure optimal braking system performance.

Quality Assurance

Power Stop rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The Geomet coating provides additional corrosion resistance to extend rotor life. While no specific warranty information is provided, Power Stop products are known for consistent quality and durability in demanding automotive applications.
